In the present invention, a spacer having a constant thickness or a projection having a constant height provided on the glass surface is provided between two vacuumed glass surfaces. The density of the spacers or protrusions should be set according to the strength of the glass.
The shape is preferably spherical, cubic, or columnar, but is not limited as long as the height is constant. The contact with the glass plate may be a point or a line, or a surface with a small area.

In the glass configured as described above, heat is not transferred by convection in the vacuum layer, the heat transfer area of the spacers or protrusions is small, and only radiant heat contributes to conduction.

The adhesive 4 is applied to the glass plate 1 except for the opening 5 around the glass plate 1, and the glass-made spherical spacers 2 are sprinkled on the surface of the other glass plate 1. It shows a state of overlapping and adhering. FIG. 2 is a reference diagram showing a state after sealing the opening 5 in a vacuum in the latter half of the assembly. The laminated glass plates are put in an airtight chamber, air is removed, and the opening 5 is sealed with the adhesive 4 while the air is released, and when the sealing material is cured, it is returned to the atmosphere. FIG. 3 is a cross-sectional view of a surface including the opening 5 of FIG. FIG. 4 shows a cross section of the vacuum opening 5 sealed with the adhesive 4. FIG. 5 shows an example in which a glass plate 1 ′ provided with a protrusion 3 on one side is used instead of the spacer 2. If the height of the spacers or protrusions is 50 microns or less, they cannot be seen with the naked eye. An adhesive that does not generate gas during sealing, for example, glass having a melting point lower than that of a plate glass or a spacer is used as an adhesive, and the opening 5 is sealed by fusing at a high temperature in a vacuum without providing the opening 5. No clothes are needed.

Even if a vacuum is drawn between the two glass plates, the force that keeps them at a fixed interval works, so even if the glass plate is thin, it will not break. Therefore, it is possible to make a large area, and since the front and back surfaces are reinforced with each other in a suctioned state, the strength of almost the total thickness of both can be obtained. The two do not have to be flat as long as the distance between the two is parallel. The spacers or protrusions can be adjusted in density and size to be invisible to the naked eye from both sides of the glass. On the contrary, the shape can be designed to be opaque or colored to give it a decorative effect.
