    Abstract: 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.

    Abstract: The objective is to propose a production method of multiple panes which can be simple and nevertheless produce a multiple pane in its finished state which does not include any undesired protrusion from an external surface of a glass panel. The production method includes: hermetically bonding, with a sealing member, peripheries of paired glass panels disposed facing each other at a predetermined distance to form a space to be hermetically enclosed between the glass panels; evacuating air from the space through an outlet to make the space be in a reduced pressure state; subsequently dividing the space by a region forming member disposed inside the space to form a partial region which do not include the outlet; and subsequently cutting out the partial regions by cutting the pair of glass panels.

    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.
