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: A gas adsorption unit includes a getter, a package encapsulating the getter, and a low-melting member. The low-melting member is heated, and thereby melted, at a temperature lower than a melting point of the package to bond a connector including the low-melting member onto the package. Next, the low-melting member that has melted is cooled and cured. Then, thermal stress resulting from a difference in thermal expansion coefficient between the package and the connector is caused to the package connected to the connector, thereby breaking the package open.

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: The method for manufacturing the gas adsorption unit includes a preparation step, an activation step, and a sealing step. The preparation step is a step of wrapping a getter with a package material. The activation step is a step of heating the getter wrapped with the package material to activate the getter. The sealing step is a step of melting the package material by heating the package material so as to seal, with the package material, the getter activated in the activation step.

Abstract: A manufacturing method of a glass panel unit of the present invention includes a bonding step, a pressure reduction step, and a sealing step. In the bonding step, a first substrate and a second substrate are hermetically bonded together with a seal having a frame shape. In the pressure reduction step, a pressure in an inside space formed between the first substrate and the second substrate is reduced through an exhaust port. In the sealing step, sealant melted is dropped toward the exhaust port, thereby sealing the exhaust port with the sealant.

Abstract: A glass panel unit includes: a sealing member arranged between a first panel and a second panel, which are arranged to face each other with a predetermined gap left between themselves, to hermetically bond the first panel and the second panel together; and an internal space sealed heimetically with the first panel, the second panel, and the sealing member. The glass panel unit further includes a spacer arranged in the internal space so as to be in contact with the first panel and the second panel. The spacer includes a plurality of resin layers that are stacked one on top of another in a direction in which the first panel and the second panel face each other. At least any two of the plurality of resin layers have different elastic moduli.

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 including a wired glass pane and a second substrate including a non-wired glass pane with a first sealant in a frame shape 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 the second sealant with an infrared ray externally incident through the second substrate to seal the exhaust port up with the second sealant that has melted.

Abstract: A glass panel unit includes a first glass panel, a second glass panel, a sealing portion in a frame shape, and a getter. The sealing portion hemietically bonds together respective peripheral portions of the first glass panel and the second glass panel. An inner space is formed at a reduced pressure between the first glass panel and the second glass panel. The getter is arranged in the inner space. The getter is arranged in a frame region extending along the sealing portion and located within a predetermined distance from each peripheral edge of the glass panel unit, so as to be covered with a building component frame.
