Document Type and Number:
Japanese Patent JP6854453
Kind Code:
B2
Abstract:
An object of the present invention is to provide a manufacturing method of a glass panel unit and a manufacturing method of a glass window including the glass panel unit which easily realize both a reduction of thermal conduction and securing of a space maintaining function. A manufacturing method of a glass panel unit (10) includes an adhesive disposing step of disposing a thermal adhesive, a pillar disposition step of disposing a plurality of pillars (70) on the first panel (20). Each of the plurality of pillars (70) includes a plurality of resin layers (71) to (73) stacked on one another. The manufacturing method further includes an opposite disposition step of disposing a second panel (30) to face the first panel (20), an inside space forming step of melting the thermal adhesive to form an inside space (500) between the first panel (20) and the second panel (30), a pressure reducing step of reducing a pressure in the inside space (500), and a reduced-pressure space forming step of sealing the inside space (500) to form a reduced-pressure space. In each of the plurality of pillars (70), a contact area being in contact with the first panel (20) and being included in the resin layer (71) which is in contact with the first panel (20) is different from a contact area being in contact with the second panel (30) and being included in the resin layer (73) which is in contact with the second panel (30).
