- the windowpane according to this embodiment can provide the following effects.
- the central regions 212 and 222 where the connection terminals 3 are arranged may be locally heated to a high temperature because current is applied intensively.
- the thickness of the central regions 212 and 222 where the connection terminals 3 are arranged is increased, so the resistance per unit area of these regions 212 and 222 is reduced. Therefore, even if the current is applied intensively, the generated heat can be reduced, so that the central region can be prevented from becoming locally hot.
- the defogger 2 is made of silver (electric resistivity: 1.6 ⁇ 10 ⁇ 8 ⁇ m), the width of the defogger is 30 mm, and the thickness of the central regions 212 and 222 is about 20 ⁇ m, the central The resistance value per unit area of the regions 212 and 222 is about 1.5 ⁇ /m 2 (the resistance value per bus bar unit length is about 0.45 ⁇ /dm), and the heat generation amount per unit area is 114 W/m 2 .
- the thickness of the upper regions 211, 221 and the lower regions 213, 223 is about 10 ⁇ m, the resistance per unit area of these regions is about 2.0 ⁇ /m 2 (per unit length of bus bar).
- the resistance value is about 0.90 ⁇ /dm), and the heat generation amount per unit area is 152 W/m 2 . Therefore, the amount of heat generated per unit area in the central regions 212 and 222 can be made smaller than in the other regions, and local high temperatures can be suppressed.
- the metal such as silver forming the busbars 21 and 22 has a higher heat reflectance than the glass plate 1, so it is less heated than the glass plate 1 when heated in a heating furnace. Therefore, when slowly cooled, a difference in contraction occurs between the busbars 21 and 22 and the glass plate 1, and the glass plate 1 is distorted in the vicinity of the busbars 21 and 22, which may cause perspective distortion. On the other hand, for example, it is conceivable to widen the width of the area in which the connection terminal 3 is provided in the busbars 21 and 22, but there is a problem that the area in which perspective distortion occurs becomes wide.
- the width of the central regions 212, 222 is made substantially the same as that of the upper regions 211, 221 and the lower regions 213, 223, so that the region where perspective distortion occurs can be reduced.
- the central regions 212 and 222 can be made wider than the other regions, even in such a case, if the central regions 212 and 222 are made thicker than the other regions, the central regions 212 and 222 can be made wider. This can be minimized even if the width of H.222 is increased. Therefore, perspective distortion can be suppressed.
- the configuration of the busbars 21 and 22 as in this embodiment is particularly advantageous.
- the widths of the central regions 212 and 222 are the same as those of the upper regions 211 and 221 and the lower regions 213 and 223, but they do not have to be exactly the same. can also Also, the width of the central regions 212,222 can be narrower than the width of the upper regions 211,221 and the lower regions 213,223.
- the central regions 212 and 222 are made thicker than the upper regions 211 and 221 and the lower regions 213 and 223 in order to reduce the resistance value per unit area of the central regions 212 and 222.
- the method for reducing the resistance value per unit area of the central regions 212 and 222 is not limited to this.
- different materials can be used in the central regions 212,222 and the upper and lower regions 211,221 and 213,223. That is, the resistance of the material forming the central regions 212 and 222 can be lower than the resistance of the material forming the upper regions 211 and 221 and the lower regions 213 and 223 .
- the central regions 212, 222 can be formed of silver and copper
- the upper regions 211, 221 and lower regions 213, 223 can be formed of aluminum, zinc, or other materials having higher electrical resistivity than silver or copper.
- the overall thickness of the central regions 212, 222 to which the connection terminals 3 are attached is made larger than the upper regions 211, 221 and the lower regions 213, 223. For example, it is sufficient that only the thickness of the portion where the connection terminal 3 is attached is increased, and as a result, the resistance value per unit area of the central regions 212 and 222 is decreased.
- the positions of the regions where the connection terminals 3 are provided are not particularly limited.
- the regions 212 and 222 in which the connection terminals 3 are provided are formed between the upper regions 211 and 221 and the lower regions 213 and 223.
- the busbars 21 and 22 are divided into a plurality of regions. , should be the first region of the present invention where the connection terminal 3 is provided, and the resistance per unit area should be smaller than that of the other region.
- connection terminal 3 shown in the above embodiment is merely an example, and various configurations are possible as long as it is a configuration that allows current to be applied to the bus bars 21 and 22 .
- the method of supplying current to the connection terminals 3 is not particularly limited.
- a connector or the like to which a conductive cable is connected can be fixed to the connection terminals 3 .
- the vehicle window glass of the present invention is applied to the rear glass, but it can also be applied to the side glass.

SiO2:70~73質量%
Al2O3:0.6~2.4質量%
CaO:7~12質量%
MgO:1.0~4.5質量%
R2O:13~15質量%(Rはアルカリ金属)
Fe2O3に換算した全酸化鉄(T-Fe2O3):0.08~0.14質量%
熱線吸収ガラスの組成は、例えば、クリアガラスの組成を基準として、Fe2O3に換算した全酸化鉄(T-Fe2O3)の比率を0.4~1.3質量%とし、CeO2の比率を0~2質量%とし、TiO2の比率を0~0.5質量%とし、ガラスの骨格成分(主に、SiO2やAl2O3)をT-Fe2O3、CeO2及びTiO2の増加分だけ減じた組成とすることができる。

バスバー21,22において、接続端子3が設けられる領域の位置は特には限定されない。上記実施形態では、上部領域211,221と下部領域213,223との間に、接続端子3が設けられる領域212,222を形成しているが、例えば、バスバー21,22を複数の領域に分け、いずれか1つの領域が、接続端子3が設けられる本発明の第1領域とし、他方の領域よりも単位面積当たりの抵抗が小さくなっていればよい。
上記実施形態で示した接続端子3の構成は、一例であり、バスバー21,22に電流を印加できるような形態であれば、特には種々の形態を取りうることができる。また、接続端子3への電流の供給方法も特には限定されず、例えば、導電ケーブルが接続されたコネクタなどを、接続端子3に固定することもできる。
