PROBLEM TO BE SOLVED: To obtain a glass composition for sealing having a low thermal expansion coefficient and good flowability at a temperature of not higher than 600°C while satisfying environmental requirements in recent years. SOLUTION: The glass composition for sealing contains, by mass, 60 to <77% of Bi<SB>2</SB>O<SB>3</SB>, 5 to 20% of B<SB>2</SB>O<SB>3</SB>, 3 to 15% of ZnO, and >1 to 7% of SiO<SB>2</SB>as glass components, and has a thermal expansion coefficient of ≤100×10<SP>-7</SP>/°C within a temperature range of 30-300°C.
