Resistive paste comprising oxides of ruthenium, lead, iron and zinc
 Disclosed herein is resistive paste containing conductive powder, which is composed of iron oxide, ruthenium oxide, lead oxide and zinc oxide, glass frit, and organic varnish. The conductive powder contains 10 to 25 atomic percent of iron oxide in terms of Fe atoms, 25 to 34 atomic percent of ruthenium oxide in terms of Ru atoms, 25 to 34 atomic percent of lead oxide in terms of Pb atoms, and 10 to 25 atomic percent of zinc oxide in terms of Zn atoms. According to this resistive paste, it is possible to obtain a resistor with small sliding noise at a low cost.
