<p><P>PROBLEM TO BE SOLVED: To provide a thick membrane resistor paste which is superior in acid resistance by using SiO<SB>2</SB>-Bi<SB>2</SB>O<SB>3</SB>-BaO system non-lead non-alkaline glass having a specific range of bismuth content as a binder glass of the thick membrane resistor paste and in which three layers of the electrode part, resistor part and surface coat part can be fired simultaneously and which can contribute to the earth environment protection. <P>SOLUTION: This is a thick membrane resistor paste made mainly of a conductive powder, glass frit, and an organic vehicle. The glass frit is constituted of a composition in weight ratio of 1% or less alkaline metal, 10-30% Bi<SB>2</SB>O<SB>3</SB>, 25-40% SiO<SB>2</SB>, 30-40% BaO, 5-7% ZnO, 4-7% Al<SB>2</SB>O<SB>3</SB>, and 0.01-8% B<SB>2</SB>O<SB>3</SB>, and does not contain PbO. <P>COPYRIGHT: (C)2003,JPO</p> |
