Document Type and Number:

WIPO Patent Application WO/2018/062131

Kind Code:

A1

Abstract:

The present invention addresses the problem of providing: a method for producing a glass panel unit, said method suppressing destruction of the reduced-pressure state of an internal space in the glass panel unit; a glass panel unit; and a glass window provided with the same. The glass panel unit is provided with a first panel (10), a second panel (20), a frame (50), and a reduced-pressure space (600). The reduced-pressure space (600) is formed by being surrounded by the first panel (10), the second panel (20), and the frame (50), excluding an evacuation path through which air can be evacuated to an external space, the reduced-pressure space (600) being sealed in a reduced-pressure state. In a state in which an internal space (6) is formed, a seal (5) has a protruding portion (500) positioned on the outer side of the edge of a first surface (1a) of a first substrate (1) and the edge of a second surface (2a) of a second substrate (2), the length (L1) of the protruding portion (500) in the thickness direction of the first substrate (1) and second substrate (2) being greater than a prescribed interval (L0).
