Abstract: A first glass substrate, a die including a penetrating space, a seat member, and a punching member are set so as to be arranged in this order. Subsequently, the seat member is punched by the punching member to remove part from the seat member through the penetrating space of the die. The part removed, is placed on the first glass substrate by the punching member so as to allow the part to serve as at least one spacer. Thereafter, the second glass substrate is placed on the first glass substrate with the at least one spacer in-between to form a glass panel unit.

Abstract: A pillar delivery method is a method for delivering a plurality of pillars onto a substrate, including a glass panel, to manufacture a glass panel unit. The pillar delivery method includes an irradiation step, a holding step, and a mounting step. The irradiation step includes setting, over a holder, a sheet for use to form pillars and irradiating the sheet with a laser beam to punch out the plurality of pillars. The holding step includes having the plurality of pillars, which have been punched out of the sheet, held by the holder. The mounting step includes picking up some or all of the plurality of pillars from the holder and mounting the pillars onto the substrate.

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.
