RESISTOR

摘要

A resistor of excellent acid resistance that enables one-time simultaneous firing of three layers of electrode part, resistance element part and surface coat part and contributes toward global environment is obtained by nonleading a thick-film resistance element paste for resistor. In particular, a resistor provided with substrate (1), resistance element (3), electrode (2) connected to the resistance element (3) and precoat (4) covering the resistance element (3) is produced by using in the formation of resistance element a thick-film resistance element paste comprising, as main components, conductive powder, glass frit and an organic vehicle wherein the glass frit is composed of, in terms of weight ratio, 1% or less of an alkali metal, 10 to 30% of Bi2O3, 25 to 40% of SiO2, 30 to 40% of BaO, 5 to 7% of ZnO, 4 to 7% of Al2O3 and 0.01 to 8% of B2O3 and does not contain PbO.
