Abstract: A manufacturing method of a glass panel for a glass panel unit includes a melting step, a spreading step, an annealing step, a cutting step, and a spacer disposition step. The spacer disposition step is a step of disposing spacers onto a glass sheet and is performed by a spacer disposition device prior to the cutting step.

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: A vacuum glass panel includes a first glass plate, a second glass plate facing the first glass plate, a frame member having a frame shape and bonding the first glass plate to the second glass plate, and a heat reflective film disposed on an inner surface of the first glass plate. A vacuum space is provided between the first glass plate and the second glass plate. The heat reflective film separates the first glass plate from the vacuum space without a gap. The frame member is in contact with the first glass plate.

Abstract: The glass panel unit includes a first glass substrate, a second glass substrate, a sealing member, an inside space, and a plurality of spacers. The inside space is hermetically enclosed by the first glass substrate, the second glass substrate, and the sealing member, and has reduced pressure. The plurality of spacers are placed in the inside space. At least one of the first glass substrate and the second glass substrate is a wire-embedded glass panel with a wire structure embedded therein. The plurality of spacers are arranged so as to overlap with part of the wire structure in a plan view.

Abstract: A first glass substrate and a second glass substrate which are placed to face each other with a seal member in-between are bonded to each other with the seal member. Subsequently, the first glass substrate, the seal member, and the second glass substrate are cut collectively along a cut plane passing through the seal member from one of the first glass substrate and the second glass substrate bonded to each other. Thereby, a glass panel unit is manufactured.

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 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.

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.
