が提案され、一部において使用されている。On the other hand, recently, there is a tendency that a window glass plate of an automobile is formed with a large area, and a heat ray such as direct sunlight is incident through the window surface to cause an increase in temperature inside the vehicle. Has occurred. In order to eliminate such inconvenience as much as possible, there has been proposed a method of applying a metal thin film having a high heat ray reflection property to a glass plate to suppress the inflow of heat rays into the vehicle, and it has been partially used.

It is sandwiched between metal oxides such as Bi 2 O 3 and is used in a form in which interference is utilized to reduce reflection by a metal thin film and, at the same time, durability is improved.

利得が得られなくなるという問題があった。When a metal thin film such as Ag is used as a heat ray reflective film, it has electric conductivity and has a sheet resistance of several Ω / □ to 10 Ω / □. The electromagnetic shielding property is accordingly high. On the other hand, as described above, since the radio wave is an electromagnetic wave, when the above-mentioned metal thin film heat ray reflective film is applied, the radio wave is blocked by the heat ray reflective film having a high electromagnetic shielding property. There is a problem in that the gain characteristic during transmission and reception is deteriorated and a necessary and sufficient gain cannot be obtained.

Alternatively, in addition to glass in which a scratch-resistant plastic film is attached to the inner surface of the glass plate, a single-layer glass having a single-layer structure can be used.

Particularly, it is more preferable if it is 50 kΩ / □ or more.

上のシート抵抗値を得ることができる。The heat ray shielding film 5 in the present invention needs to be formed of a thin film having a high resistance value in order to eliminate the electromagnetic shielding characteristics and prevent the diffusion of electromagnetic waves. Specifically, a heat ray-shielding film whose main component is a metal oxynitride composed of M1 and M2 is used. The specific resistance is higher than that of conventional Ag metal, and a sheet resistance value of 20 kΩ / □ or more can be obtained by selecting an appropriate film thickness.

原子比で５０％以上であることが好ましい。In order to obtain sufficient heat ray shielding performance in the heat ray shielding film 5, the total amount of M2 is preferably 50% or more in atomic ratio with respect to the total amount of M1.

い。When the content ratio of M2 is relatively large (for example, the total amount of M2 is 50% or more with respect to the total amount of M1 in atomic ratio), the visible light transmittance is 20 kΩ / A sheet resistance value of □ or more is obtained, and a heat ray blocking function is sufficiently exhibited, which is preferable.

In the range of 0% or more), the heat ray blocking performance is slightly inferior, but the sheet resistance value of 500 kΩ / □ is easily obtained because of high specific resistance, which is particularly optimum. That is, since the absorption of visible light is small, the film thickness is increased to maintain a high light transmittance and sufficient heat ray blocking performance is obtained, and even if the film thickness is increased, a high sheet resistance of 500 kΩ / □ or more is obtained. can get.

内環境の向上に効果的に寄与させうる。In this way, even if the heat ray-shielding film 5 is arranged, since the heat ray-shielding film 5 itself is formed of a non-conductive thin film having a high resistance value, the electromagnetic shielding characteristic is suppressed. It does not impair the gain of various transceivers mounted on the vehicle. Further, since the surface of the glass 1 is covered with the heat ray shielding film 5, it is possible to effectively prevent heat such as direct sunlight from entering the inside of the vehicle to raise the temperature inside the vehicle, and to reduce energy consumption such as cooling load reduction. While taking the measures, it can effectively contribute to improving the environment inside the vehicle.
