GLASS PANEL UNIT MANUFACTURING METHOD, BUILDING COMPONENT MANUFACTURING METHOD, GLASS PANEL UNIT MANUFACTURING SYSTEM, AND GLASS PANEL UNIT
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.
