Furthermore, in order to make a double-layer glass shoji, a step of attaching a ridge to the peripheral portion of the double-layer glass is required.

  In recent years, with the diversification of the designs of houses and various other building structures, a multi-layer glass shoji structure that is further superior in daylighting performance, designability and openness and has little heat loss has been desired. In particular, in the multi-layer glass shoji used for the inner window, the shoji can be slimmed, and a design with high design and a feeling of openness has been desired.

  On the other hand, when manufacturing a window screen using conventional multilayer glass, for example, a multilayer glass having a hollow layer in the middle by separating two glass plates using a spacer is manufactured. Since the double-glazed glass manufacturing process and the double-glazed assembling process of manufacturing the double-glazed glass shoji by assembling the glazing at the peripheral edge of the laminated glass, there are many parts and many assembling steps.

  In addition, in the double-glazed glass using three glass plates described in Patent Document 3, it is difficult in terms of structure to install a cocoon around the structure, and the lighting performance, designability and openness are difficult. It was difficult to increase the feeling.

  In addition, if another inner window is installed on the indoor side of the windows of existing houses, buildings, etc., and double windows are used to improve soundproofing, heat insulation, and crime prevention, the shoji used for the inner window However, there has been a demand for a material having a thinner thickness, a wide opening, a feeling of opening, and an excellent design.
