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 first substrate, having an evacuation port, and a second substrate are bonded together with a first sealing material in a frame shape interposed between them to create an internal space. The internal space is evacuated through the evacuation port, and the evacuation port is sealed up with the internal space kept evacuated. At this time, a second sealing material inserted into the evacuation port is heated and melted while being pressed toward the second substrate such that the evacuation port is sealed up with the second sealing material melted. The evacuation port and the second sealing material have dissimilar shapes when viewed along the center axis of the evacuation port in a state where the second sealing material has been inserted into the evacuation port but has not melted yet.

Abstract: A method for manufacturing a pillar supply sheet is a method for manufacturing a pillar supply sheet including a plurality of pillars, a carrier sheet, and an adhesion layer between each of the pillars and the carrier sheet, the method including a pillar forming step. The pillar forming step is a step of forming the plurality of pillars by subjecting the base member to an etching process or a laser irradiation process and removing an unnecessary portion from the base member after the process.

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 and expanding a second sealant, inserted into the exhaust port, by heating the second sealant and thereby sealing the exhaust port up with the second sealant expanded to the point of coming into contact with a dam arranged in the inner space.
