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: A method for manufacturing a glass panel unit includes an adhesive disposing step, a glass composite generation step, an internal space forming step, an evacuation step, and an evacuated space forming step. The adhesive disposing step includes disposing a thermal adhesive on a second panel. The glass composite generation step includes generating a glass composite including a first panel, the second panel, and the thermal adhesive. The internal space forming step includes heating the glass composite to melt the thermal adhesive to form internal spaces (a first space and a second space). The evacuation step includes exhausting gas from the internal space to evacuate the internal space. The evacuated space forming step includes heating and applying force to part of a first portion or a second portion to deform the part to close an evacuation path to form an evacuated space hermetically closed.

Abstract: A work in progress includes: a pair of glass substrates arranged to face each other; a peripheral wall having a frame shape and disposed between the pair of glass substrates; a boundary wall; and an evacuation port. The boundary wall hermetically separates an internal space, surrounded with the pair of glass substrates and the peripheral wall, into an evacuation space, a buffer space, and a ventilation space. The evacuation port connects the ventilation space to an external environment. The evacuation space and the buffer space have a lower internal pressure than the ventilation space. A predetermined part, including the evacuation space but excluding parts covering the buffer space and the ventilation space, of the work in progress, forms the glass panel unit.

Abstract: A glass panel unit having an exhaust pipe not protruding from the glass panel unit and an evacuation port tightly sealed, a glass window. A glass panel unit includes a first panel, a second panel, a seal member having a frame shape, a pore sealing material, and a bonding portion. The seal member hermetically bonds a peripheral portion of the first panel and a peripheral portion of the second panel together such that a hermetically sealed space in an evacuated state is formed between the first panel and the second panel. The pore sealing material hermetically seals an evacuation port formed in one of the first panel and the second panel. The bonding portion is bonded to the first panel and the second panel at part of a peripheral portion of the evacuation port and to suppress the first panel and the second panel from separating from each other.

Abstract: A pillar mounting method includes an accommodation step, a mounting step, and a displacement step. The accommodation step is a step of accommodating a plurality of pillars in storage with the plurality of pillars being stacked on each other. The mounting step is a step of pushing one pillar of the plurality of pillars accommodated in the storage out of the storage and mounting the one pillar on a substrate including a glass pane. The displacement step is a step of changing a relative location between the substrate and the storage. The mounting step and the displacement step are alternately repeated to mount the plurality of pillars in a predetermined arrangement on the substrate such that the plurality of pillars are apart from each other.

Abstract: The glass panel unit includes a first glass panel, a second glass panel, a seal, an evacuated space, and a spacer. The second glass panel is placed opposite the first glass panel. The seal with a frame shape hermetically bonds the first glass panel and the second glass panel to each other. The evacuated space is enclosed by the first glass panel, the second glass panel, and the seal. The spacer is placed between the first glass panel and the second glass panel. The spacer is a stack of two or more films. At least one film of the two or more films contains a polymer having a viscoelastic coefficient at 400° C. larger than 500 MPa.

Abstract: A glass panel unit includes a first panel, a second panel, a frame body and a reduced pressure space. The reduced pressure space is surrounded with the first panel, the second panel and the frame body other than an exhaust path capable of exhausting gas to an outside, and sealed in a reduced pressure state. In a state where the inner space has been formed, the seal includes a protruding portion positioned outside of edges of a first surface of a first substrate and a second surface of a second substrate. The protruding portion has a length, along the thickness directions of the first substrate and the second substrate, longer than a prescribed interval.
