If the adhesive strength is reduced, there is a risk that the vacuum glass panel may be damaged, or air may enter the vacuum space and heat insulation may be reduced. Therefore, it is important to increase the adhesive strength at the bonded portion of the glass plate. In particular, in a vacuum glass panel in which a heat reflecting film is provided on the inner surface of a glass plate, it is more required to improve the adhesive strength of the glass plate while maintaining heat insulation by the heat reflecting film and vacuum.

- the vacuum glass panel 1 includes the vacuum space 50 and the heat reflecting film 11, heat is not easily transmitted in the thickness direction of the vacuum glass panel 1. Therefore, the vacuum glass panel 1 is excellent in heat insulation.

- the adhesive strength of this portion is improved.
- the heat reflecting film 11 is provided so as to face the entire vacuum space 50, the heat insulation is improved.
- the area where the frame 30 is in contact with the first glass plate 10 is preferably larger than the area where the frame 30 is in contact with the heat reflecting film 11. Thereby, the adhesive strength between the frame 30 and the first glass plate 10 is further improved.
- the distance at which the frame 30 and the first glass plate 10 are in contact is preferably longer than the distance at which the frame 30 is in contact with the heat reflecting film 11.
- the edge 11 a of the heat reflecting film 11 is in contact with the side portion of the frame body 30.
- the frame body 30 is provided on the first glass plate 10.
- the frame 30 does not ride on the heat reflecting film 11.
- the heat reflecting film 11 separates the first glass plate 10 and the vacuum space 50 without a gap.
- the first glass plate 10 is not exposed to the vacuum space 50.
- the first glass plate 10 and the vacuum space 50 are completely separated by the heat reflecting film 11.
- the position of the edge 11a of the heat reflecting film 11 and the position of the side portion of the frame 30 need to match, and therefore, the manufacturing may not be easier than the structure of FIG. 2A. is there. Therefore, considering the ease of manufacture, the structure of FIG. 2A is more advantageous than the structure of FIG. 2B.
- the edge 11 a of the heat reflecting film 11 does not reach the frame body 30 and is not in contact with the frame body 30.
- the heat reflecting film 11 does not completely separate the first glass plate 10 and the vacuum space 50.
- a gap 30x is formed between the heat reflecting film 11 and the frame 30, and the first glass plate 10 faces the vacuum space 50 and is exposed at the position of the gap 30x.
- the first glass plate 10 and the frame body 30 are in direct contact with each other, so that the adhesive strength of this portion is improved, but the heat reflecting film 11 extends only partway in the vacuum space 50, so the gap 30x
- the heat insulating property is lowered. Therefore, the structure of FIGS. 2A and 2B is more advantageous than the structure of FIG. 2C.
- the edge 11a of the heat reflecting film 11 is located at the edge of the first glass plate 10 and is exposed to the outside.
- the heat reflecting film 11 separates the first glass plate 10 and the frame body 30, and the first glass plate 10 and the frame body 30 are not in contact with each other.
- the heat reflecting film 11 is provided so as to face the entire vacuum space 50, the heat insulation is improved, but the first glass plate 10 and the frame 30 are not in direct contact with each other. The adhesive strength of the is reduced. Therefore, the structure of FIGS. 2A and 2B is more advantageous than the structure of FIG. 2D.
- FIGS. 2A and 2B are more advantageous than the structure of FIGS. 2C and 2D.
- the reason is considered that the frame 30 formed of the glass adhesive is easily fused at the interface with the first glass plate 10 at the time of bonding.
- FIG. 2A and 2B can be obtained by removing a part of the heat reflecting film 11 during the manufacturing of the vacuum glass panel 1. If the heat reflecting film 11 is not removed at all, the structure shown in FIG. 2D can be obtained. When the heat reflection film 11 is excessively removed, the structure shown in FIG. 2C can be obtained.
- a glass frit having high adhesiveness to the heat reflecting film 11 is used as a glass adhesive as a base of the frame body 30. Only materials can be used. Such a glass frit material is difficult to be processed at a sufficiently low temperature, and may have a process that results in an adhesion temperature of 400 ° C.
- the glass frit material and the glass plate are in direct contact with each other without the heat reflecting film 11 interposed therebetween. Adhesiveness can be improved. In this case, for example, a low-temperature process at around 350 ° C. can be performed, and an excellent low-melting glass frit can be used as the glass frit material.
- the high adhesiveness of the 1st glass plate 10 and the frame 30 is obtained.
- the frame 30 when the heat reflecting film 11 is partially removed (for example, the structure of FIGS. 2A and 2B), there is a portion where the frame 30 and the first glass plate 10 are directly bonded. Even if the adhesion between the first glass plate 10 and the first glass plate 10 is reduced, the frame 30 can be prevented from peeling off from the first glass plate 10.
- the frame body 30 when the adhesion between the heat reflecting film 11 and the first glass plate 10 is lowered, the frame body 30 may be peeled off from the first glass plate 10 together with the heat reflecting film 11. The decrease in the adhesion between the heat reflecting film 11 and the first glass plate 10 can occur during heating, for example. Therefore, for example, in the structure of FIG.
- FIGS. 2D it is preferable to avoid heating at a high temperature in order to suppress peeling of the heat reflecting film 11, but according to the structure of FIGS. 2A and 2B, processing at a higher temperature is also possible. . Therefore, according to the structure in which the heat reflecting film 11 is partially removed as shown in FIGS. 2A and 2B, for example, a heating step (for example, described later) for bonding the first glass plate 10 and the second glass plate 20 with the frame body 30. It is also possible to improve the adhesiveness of the frame 30 by processing at a higher temperature in the first heating step).
- the heat reflection film 11 when the heat reflection film 11 is partially removed, if the removal width of the heat reflection film 11 is large as in the structure of FIG. 2C, the heat reflection film 11 exists in a portion where the glass adhesive is not provided.
