Abstract: Provided are a glass panel unit and a method for manufacturing the glass panel unit, both of which are designed to overcome the problem of poor handleability of known glass panel units with no through holes. A glass panel unit includes a first panel, a second panel, a seal, and a boundary wall. The seal has a frame shape and hermetically bonds respective peripheral edge portions of the first panel and the second panel. The boundary wall partitions an internal space into a first space as a hermetically sealed evacuated space and a second space spatially separated from the first space. The first panel has a first through hole provided through a portion, corresponding to the second space, of the first panel. The second panel has a second through hole provided through a portion, corresponding to the second space and facing the first through hole, of the second panel.

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 assembly includes a pair of glass substrates arranged to face each other, a peripheral wall, a partition, an air passage, and an evacuation port. The peripheral wall has a frame shape and is provided between the pair of glass substrates. The partition partitions an internal space, surrounded with the pair of glass substrates and the peripheral wall, into a first space and a second space. The air passage connects the first space and the second space together. The evacuation port connects the second space to an external environment. The partition has a broader width than the peripheral wall.

Abstract: A method for manufacturing a glass panel unit, which reduces the amount of a getter material to enable a gettering ability to be realized at a relatively low temperature less likely to cause damage. The method includes a step of producing a getter material by heating an unprocessed getter material at a temperature higher than a prescribed temperature Te; a step of producing a preassembled component including a first and second glass pane, a heat-fusible sealing material, an internal space, and a gas adsorbent containing the getter material, and an evacuation port; a step of forming a frame body hermetically bonding the first glass pane and the second glass pane together by melting the heat-fusible sealing material with heat; and a step of heating the gas adsorbent at the prescribed temperature Te while the internal space is evacuated by exhausting air in the internal space through 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 glass panel unit having an inner space at a reduced pressure and a building component including such a glass panel unit are provided such that no traces of an exhaust pipe are left on their outer surface. To achieve this, 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 (10) and a second substrate (20) with a first sealant (410) to create an inner space (510). The pressure reducing step includes producing a reduced pressure in the inner space (510) through an exhaust port (50) that the first substrate (10) has. The sealing step includes melting a second sealant (420) inserted into the exhaust port (50) by locally heating the second sealant (420), and deforming the second sealant (420) by pressing the second sealant (420) toward the second substrate (20), to seal the exhaust port (50) up with the second sealant (420) melted and deformed. 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 melting a second sealant inserted into the exhaust port by locally heating the second sealant, and deforming the second sealant by pressing the second sealant toward the second substrate, to seal the exhaust port up with the second sealant melted and deformed.

Abstract: A glass panel unit includes: a first panel including a glass pane; a second panel including another glass pane; a sealing portion; an exhaust port; and a printed portion. The second panel is arranged to face the first panel. The sealing portion is formed in a frame shape and hermetically bonds respective peripheral edge portions of the first and second panels to create an evacuated, hermetically sealed space between the first panel and the second panel. The exhaust port is provided for one panel selected from the first and second panels. A port sealing member hermetically seals the exhaust port. The printed portion is provided for the other panel selected from the first and second panels. The printed portion is located in an area, facing the exhaust port, of one surface of the other panel. The one surface either faces toward, or faces away from, the hermetically sealed space.

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.
