An object of the present invention is made of SnO—P 2 O 5 glass, and even when a metal double container is vacuum-sealed, the amount of generated gas is small and hermeticity is not impaired. It is to provide a glass for sealing with high reliability. The sealing glass of the present invention is a sealing glass made of SnO—P 2 O 5 glass used for vacuum-sealing an exhaust port provided in a metal double container. , 5.0 × 10 −7 Torr, the amount of gas generated when held in an environment of 500 ° C. for 30 minutes is 150 μL / g or less in terms of 0 ° C. and 1 atm.
