摘要

A lead-free glass for coating an electrode, which comprises, in mole %, 15 to 65 % of B<SUB>2</SUB>O<SUB>3</SUB>, 2 to 38 % of SiO<SUB>2</SUB>, 2 to 30 % of MgO, 5 to 45 % of MgO + CaO + SrO + BaO, 1 to 15 % of Li<SUB>2</SUB>O, 2 to 25 % of Li<SUB>2</SUB>O + Na<SUB>2</SUB>O + K<SUB>2</SUB>O, and 0 to 15 % of ZnO; and a lead-free glass for coating an electrode, which comprises, in mole %, 25 to 65 % of B<SUB>2</SUB>O<SUB>3</SUB>, 2 to 38 % of SiO<SUB>2</SUB>, 2 to 30 % of MgO, 5 to 45 % of MgO + CaO + SrO + BaO, 2 to 25 % of Li<SUB>2</SUB>O + Na<SUB>2</SUB>O + K<SUB>2</SUB>O, 0 to 30 % of Al<SUB>2</SUB>O<SUB>3</SUB>, 0 to10 % of TiO, and 0 to 15 % of ZnO.
