GLASS PANEL

摘要

Glass panel provided with a glass panel body (P1) comprising a pair of sheets of flat glass (1) disposed with a thickness-direction gap between them, a suction port (6) formed in one sheet (1A) of the pair of sheets of flat glass (1) and a clearance (V), between the pair of sheets (1), vacuum-sealed through the suction port (6); the suction port (6) being constituted by providing a through hole (1a) in the one sheet (1A), erecting a suction glass tube (7) on the hole (1a), providing a low-melting-point glass seal (S) covering the base end of the tube (7) and the peripheral edge of the hole (1a) in the one sheet (1A), and providing a closed portion (H) formed by closing the tip end of the tube (7) by heating and melting; wherein low-melting-point glass constituting a first seal (S1), corresponding to the one sheet (1A), of the seal is set smaller in thermal expansion coefficient than one sheet (1A).
