Abstract: A glass panel unit includes a first panel, a second panel, a frame body and a reduced pressure space. The reduced pressure space is surrounded with the first panel, the second panel and the frame body other than an exhaust path capable of exhausting gas to an outside, and sealed in a reduced pressure state. In a state where the inner space has been formed, the seal includes a protruding portion positioned outside of edges of a first surface of a first substrate and a second surface of a second substrate. The protruding portion has a length, along the thickness directions of the first substrate and the second substrate, longer than a prescribed interval.

Abstract: An object of the disclosure is to provide a glass panel and a glass window which are configured to stably maintain a depressurized space therein even when their spacers contain a resin. A glass panel unit of an aspect of the disclosure includes: a first glass pane; a second glass pane facing the first glass pane; a frame member which has a frame shape and which the first and second glass panes are bound together through; and spacers containing a resin and disposed between the first and second glass panes. A depressurized space is provided between the first glass pane and the second glass pane. The first and second glass panes are respectively to be exterior and interior panes. The first glass pane has lower ultraviolet transmittance than the second glass pane.

Abstract: A glass panel unit manufacturing method includes a bonding step, an exhausting step, and a sealing step. The bonding step includes bonding together, with a sealing member, a first glass panel and a second glass panel to form an inner space. The exhausting step includes exhausting air from the inner space through an exhaust pipe detachably connected to an exhaust port.

Abstract: Disclosed herein is a glass panel unit including: a first panel including at least a first glass plate; a second panel arranged to face the first panel and including at least a second glass plate; a frame member formed in a shape of a frame corresponding in shape to respective peripheral portions which extend along edges of the first panel and the second panel, and bonded to the peripheral portions; and at least one spacer provided in a vacuum space between the first panel and the second panel. The at least one spacer contains a polyimide. The polyimide has an absorption edge at which an absorption index decreases in an optical absorption spectrum ranging from an ultraviolet ray to visible radiation. The absorption edge is equal to or less than 400 nm.

Abstract: A glass panel unit includes a first pane of glass, and a second pane of glass facing the first pane of glass with the panes of glass spaced a predetermined interval apart. The glass panel includes a seal disposed between the panes of glass and joined to them in an airtight manner, and an interior space encompassed with the panes of glass and the seal. The glass panel unit includes: a partition wall disposed in the interior space and divides the interior space into a first space as a vacuum space and a second space; an air release vent formed in a first or second pane of glass and communicates with the second space; and a blocking member provided in the air release vent.
