Abstract
A thick film resistor composition, comprising a silicide powder composed of a molybdenum disilicide, a tantalum disilicide and a magnesium silicide, and an alkaline earth borosilicate glass powder dispersed in a vehicle containing a heat-depolymerizing organic polymer. The thick film resistor composition, employing this heat-depolymerizing organic polymer, can be fired in a nonoxidizing atmosphere and coexist with base metal materials such as copper electrodes. Owing to the Nb.sub.2 O.sub.5 and Ta.sub.2 O.sub.5 contained in the alkaline earth borosilicate glass powder, the thick film resistor composition is free from sheet resistivity fluctuation, according to resistor length, which would result from diffusion of the electrode material into the resistor.
