A problem that the pressing force of the sheet glass pressing the gap holding member due to the external pressure when the inside of the gap is decompressed causes a concentrated load to act on the opposed surface, which is likely to cause a Hertz crack in the sheet glass. have. Incidentally, if the pressure in the gap is reduced to about 0.1 atm or less, the external pressure applied to the outer surface of the glass sheet by the atmospheric pressure reaches approximately 10 ton / m 2 . Therefore, when the radius of the spacing member formed of the sphere is small, the Hertz crack is caused.

The outer peripheral sealing portion 4 is sealed using a low-melting glass, and the gap 3 is sealed while maintaining a reduced pressure state. Then, by interposing the spacing member S according to the present invention between the facing surfaces 2 of the two glass sheets 1,
The space between the opposing surfaces 2 is maintained at the predetermined interval. After sealing the outer peripheral sealing portion 4, the glass panel sucks the air in the gap portion 3 from the suction hole,
The suction hole is sealed and formed in a state where the pressure inside the gap 3 is detected.

してある。As shown in FIGS. 2 and 3, the spacing member S is formed integrally with the flat plate portion 7 formed so as to be able to contact the opposing surface 2 of the one glass plate 1A. The bottom portion 8a of the base portion 8 formed of a base portion 8 formed in a plane and formed so as to be able to contact the facing surface 2 of the other sheet glass 1B, and the flat plate portion 7, It is configured to form a pair of contact surface portions 5 that respectively contact the opposite surfaces 2.

It is formed. Since this boundary 9 has a small cross-sectional area, this becomes a bottleneck for heat conduction. In other words, in three-dimensional heat conduction, the amount of heat transfer is inversely proportional to the length in the heat flux direction and proportional to the cross-sectional area in that direction. I do. Therefore, the boundary part 9 can be the heat transfer resistance part 6.

As an example of the manufacturing method, it is possible to cut a glass thin plate into pieces of a predetermined shape, form one of the bases 8 by etching one surface thereof, and fuse them with another glass thin plate to integrally form the same. No. This material is optional, and may be formed of, for example, a plastic such as polypropylene, and may be made of stainless steel (eg, SUS304, S

At the same time, the two contact surfaces 5 abut against the opposing surfaces 2 of the two glass sheets 1, so that the sheet glass 1 provided by the spacing member S is sandwiched between the two glass sheets 1.
The stress concentration on the glass sheet 1 can be reduced, and breakage of the glass sheet 1 due to the stress concentration can be prevented. In addition, since the contact surface 5 of the spacing member S contacts the opposing surface 2 of the sheet glass 1 with a relatively large area, the heat transfer resistor 6 having a small heat transfer cross-sectional area is formed. The amount of heat conduction between the sheet glasses 1 can be reduced.
