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.

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.

Abstract: A method for manufacturing a glass panel unit includes a glue arrangement step, an assembly forming step, a first melting step, an evacuation step, and a second melting step. The first melting step includes melting a hot glue, bonding a first and second panel with the glue, and forming an internal space. The first melting step includes a first temperature raising step, a first temperature maintaining step including maintaining the temperature of the assembly at a temperature equal to or higher than a softening point of the hot glue, and a first temperature lowering step, which are performed in this order. The first temperature lowering step includes: an anterior temperature lowering step including lowering the temperature of the assembly; a middle temperature maintaining step including maintaining the temperature of the assembly; and a posterior temperature lowering step including lowering the temperature of the assembly, which are performed in this order.
