A sealing glass composition which has an alkali metal oxide content kept down as much as possible, and can stably join metal or ceramic members together in a temperature range of 600 to 900° C. The sealing glass composition is used to join together members each selected from the group consisting of metal members and ceramic members, and comprises, as essential components, 20 to 50 mol % of SiO<SUB>2</SUB>, 1 to 9 mol % of Al<SUB>2</SUB>O<SUB>3</SUB>, 5 to 25 mol % of B<SUB>2</SUB>O<SUB>3</SUB>, 10 to 40 mol % of BaO, and 5 to 20 mol % of SrO. ZnO content is 0 to 10 mol %. An alkali metal oxide content is not more than 5 mol %. PbO is substantially not contained. The total content of MgO, CaO, SrO, BaO and ZnO is 30 to 50 mol %.
