Abstract: A glass panel unit includes: a pair of glass panels arranged to face each other; and a frame member disposed between the pair of glass panels to hermetically bond the pair of glass panels together. The frame member includes: a body; and a reinforcing portion. The body has a frame shape and includes: a first part containing a first sealing material having a first softening point; and a second part containing a second sealing material having a second softening point that is higher than the first softening point. The reinforcing portion contains a third sealing material having a third softening point that is higher than the first softening point. The reinforcing portion is adjacent to the first part in a space surrounded with the pair of glass panels and the body.

Abstract: The assembling step is a step of preparing an assembly. The setting step is a step of setting a plurality of holder installation areas along an outer peripheral edge of the peripheral wall. The determining step is a step of determining a first area in which the slit and the peripheral wall are not adjacent to each other in the first area and a second area in which the slit and the peripheral wall are adjacent to each other. The installation step is a step of providing a holder in the first area without providing the holder in the second area.

Abstract: A glass panel unit manufacturing method includes a bonding step, an insertion step, an evacuation step, and a sealing step. The bonding step includes bonding a first substrate having an evacuation port and a second substrate together with a bonding material provided between the first substrate and the second substrate and having a frame shape to form an internal space. The insertion step includes inserting a sealing material into the evacuation port. The evacuation step includes evacuating the internal space through the exhaust passage. The sealing step includes deforming the sealing material by heating while an evacuated state in the internal space is maintained. In a state where the sealing material blocks ventilation between the evacuation port and the internal space, gas is supplied through the exhaust passage toward the evacuation port.

Abstract: A glass panel unit manufacturing method includes a punching step and a pillar mounting step. In the punching step, a punch punches at least one of a plurality of portions from a base material of a sheet to form at least one pillar. Each of the plurality of portions is surrounded by a corresponding one of a plurality of loop-shaped grooves in the base material. In the pillar mounting step, the at least one pillar is mounted on a surface of a first substrate including a glass pane.

Abstract: A work in progress includes: a pair of glass substrates arranged to face each other; a peripheral wall having a frame shape and disposed between the pair of glass substrates; a boundary wall; and an evacuation port. The boundary wall hermetically separates an internal space, surrounded with the pair of glass substrates and the peripheral wall, into an evacuation space, a buffer space, and a ventilation space. The evacuation port connects the ventilation space to an external environment. The evacuation space and the buffer space have a lower internal pressure than the ventilation space. A predetermined part, including the evacuation space but excluding parts covering the buffer space and the ventilation space, of the work in progress, forms the glass panel unit.

Abstract: A method for manufacturing a glass panel unit includes an assembling step, a bonding step, a gas exhausting step, a sealing step, and an activating step. The bonding step includes melting a peripheral wall in a baking furnace at a first predetermined temperature to hermetically bond a first glass pane and a second glass pane together with the peripheral wall thus melted. The gas exhausting step includes exhausting a gas from an internal space through an exhaust port in the baking furnace to turn the internal space into a vacuum space. The sealing step includes locally heating to a temperature higher than a second predetermined temperature, and thereby melting, either a port sealing material or an exhaust pipe to seal the exhaust port and thereby obtain a work in progress. The activating step includes activating a gas adsorbent after the sealing step to obtain a glass panel unit.

Abstract: An assembly includes: a pair of glass substrates; a peripheral wall disposed between the glass substrates; partitions; an evacuation port; and air passages. The partitions are provided to partition an internal space, surrounded with the glass substrates and the peripheral wall, into an evacuation space and a ventilation space. The evacuation port connects the ventilation space to an external environment. The air passages are used to evacuate the evacuation space through the evacuation port. The air passages include particular air passages arranged in a second direction perpendicular to a first direction, in which the glass substrates face each other, to constitute a ventilation path running through the internal space in the second direction.

Abstract: A glass panel unit manufacturing method includes a bonding step, a pressure reducing step, and a sealing step. The bonding step includes bonding together a first substrate and a second substrate with a first sealant to create an inner space. The pressure reducing step includes producing a reduced pressure in the inner space through an exhaust port that the first substrate has. The sealing step includes irradiating a second sealant, inserted into the exhaust port, with an infrared ray through a region, where a low emissivity film is nonexistent, of the second substrate.

Abstract: A glass panel unit includes: a first substrate including a first glass panel; a second substrate including a second glass panel; and a frame-shaped sealing portion that is hermetically bonded to the first substrate and the second substrate. The sealing portion creates an evacuated space between the first substrate and the second substrate. When viewed from a region where the second substrate is positioned with respect to the first substrate, the first substrate includes a part arranged to stick out of an edge of the second substrate. The part includes a mounting portion used to mount the glass panel unit onto a vehicle.
