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 includes a stack of two or more films including at least one resin film.

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: In s glass panel unit, a pitch of pillars is determined such that a distortion of a first panel and second panel is smaller than an interval between the first panel and the second panel. The distortion is calculated based on the interval between the first panel and the second panel, load loading compression fracture per one pillar of the multiple pillars, Young's moduli of the first panel and the second panel, thicknesses of the first panel and the second panel, and Poisson's ratios of the first panel and the second panel.

Abstract: An object of the disclosure is to provide a manufacturing method of a glass panel unit which is simply performable. A manufacturing method of a glass panel unit of an aspect of the disclosure includes housing a preassembled component including a first glass panel, a second glass panel, and a frame member disposed between the first and second glass panels to hermetically bond the first glass panel to the second glass panel in a chamber and evacuating the chamber to achieve a reduced pressure state. The frame member has an exhaust port communicating with inside and outside spaces. The chamber has a thermally conductive pressing part movable to press the first and second glass panels in a direction in which the first and second glass panels approach each other. The manufacturing method includes heating the frame member by a heater to deform the frame member to close the exhaust port.

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.

Abstract: The glass panel unit is a predetermined part separated from a completed assembly obtained by subjecting a temporary assembly to a predetermined process. In the temporary assembly, the inside space (500) enclosed by the first and second glass substrates and the frame is divided into the first space and the second space with the partition and the gas adsorbent is inside the first space. The predetermined process includes: converting the first space into the evacuated space by evacuating the first space through the gas passage, the second space, and the outlet; and changing a shape of the partition to close the gas passage to form the seal enclosing the evacuated space. The predetermined part includes: a first and second glass panels being parts of the first and second glass substrates; the seal; the evacuated space; and the gas adsorbent.
