<p><P>PROBLEM TO BE SOLVED: To provide a glass composition capable of realizing a low resistance lead-free thick film resistor exhibiting excellent temperature characteristics (TCR) in which aging is suppressed. <P>SOLUTION: The glass composition contains CaO, B<SB>2</SB>O<SB>3</SB>, SiO<SB>2</SB>and MnO and has compositional ratio of 10-30 wt% of CaO, 25-40 wt% of B<SB>2</SB>O<SB>3</SB>, 15-30 wt% of SiO<SB>2</SB>, and 10-40 wt% of MnO. The glass composition is mixed with an organic vehicle together with a conductive material to produce thick film resistor paste. The thick film resistor paste contains at least one kind selected from CuO, Cu<SB>2</SB>O, MnO<SB>2</SB>, Mn<SB>3</SB>O<SB>4</SB>, V<SB>2</SB>O<SB>5</SB>, GaO, Dy<SB>2</SB>O<SB>3</SB>, Sm<SB>2</SB>O<SB>3</SB>, Lu<SB>2</SB>O<SB>3</SB>, La<SB>2</SB>O<SB>3</SB>, ZnO, and Bi<SB>2</SB>O<SB>3</SB>as an additive. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
