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 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 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.

Abstract: Provided is a glass panel unit that reduces the chances of an electric wire extended being disconnected. A glass panel unit includes a first panel, a second panel, a seal, a connecting void, and an electric wire. The first panel includes a first glass pane. The second panel includes a second glass pane and is arranged to face the second glass pane. The seal has a frame shape and hermetically bonds respective peripheral edge portions of the first panel and the second panel to create an internal space between the first panel and the second panel. The connecting void is provided for a portion, other than a portion facing the internal space, of at least one of the first panel or the second panel. The electric wire is extended from the internal space to the connecting void by passing through the seal.

Abstract: A sealing head includes a frame, an intake unit, a pressing pin, and a non-contact heater. The frame is configured to be detachably attached to a work in progress of a glass panel unit. The intake unit, the pressing pin, and the non-contact heater are supported by the frame. The work in progress includes a first substrate, a second substrate, a bonding part, and an internal space. The first substrate has an evacuation port. The bonding part bonds the first substrate and the second substrate together. The internal space is formed by being surrounded by the first substrate, the second substrate, and the bonding part. The internal space is communicated with the evacuation port. The pressing pin is configured to press, toward the second substrate, a sealing material which is heat fusible and which is inserted into the evacuation port. The non-contact heater is configured to locally heat the sealing material in a non-contact manner via the second substrate.

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 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.
