Title: METHOD FOR PRODUCING GLASS PANEL UNIT, AND METHOD FOR PRODUCING GLASS WINDOW
Abstract:
The present invention addresses the problem of producing glass panel units of various sizes while minimizing costs. This method for producing a glass panel unit is equipped with a preparation step, a pillar arrangement step, a joining step, a sealing step, and a cutting step. The preparation step involves preparing a first substrate (1) and a second substrate (2) which has a smaller external shape than does the first substrate (1). The pillar arrangement step involves arranging a plurality of pillars (4) on the first substrate (1). The joining step involves joining the outer-peripheral section of the second substrate (2) to the first substrate (1) while the plurality of pillars (4) are sandwiched between the second substrate (2) and the first substrate (1). The sealing step involves sealing the interior space (S1) between the second substrate (2) and the first substrate (1) in a depressurized state. The cutting step involves cutting the first substrate (1) along the external shape of the second substrate (2).
