PROBLEM TO BE SOLVED: To provide a glass powder which has reduced shrinkage on firing. SOLUTION: The glass powder is essentially made up of, by mass, 20 to 98% SiO<SB>2</SB>+B<SB>2</SB>O<SB>3</SB>+Bi<SB>2</SB>O<SB>3</SB>, 0 to 18% Al<SB>2</SB>O<SB>3</SB>, 0 to 77% MgO+CaO+SrO+BaO+ZnO, 0 to 75% PbO, 0 to 30% Li<SB>2</SB>O+Na<SB>2</SB>O+K<SB>2</SB>O, 0 to 19% TiO<SB>2</SB>+ZrO<SB>2</SB>and 0 to 5% SnO<SB>2</SB>+CeO<SB>2</SB>+CuO. In the glass powder, the volumes-based means diameter D<SB>50</SB>is≥1.5μm, and the specific surface areaΘby a gas adsorption BET method is≥6 m<SP>2</SP>/g. COPYRIGHT: (C)2003,JPO
