To provide a thick-film resistor composition which is suitable for use in rheostats and which has excellent electrical characteristics, possesses low contact resistance, and yields stable conductive coupling during sliding between the slider and the resistor sliding path. 10 to 50wt.% an electrically conductive pyrochlore with a specific surface of up to 7 m<2>/g, 20 to 70 wt.% a glass binder containing no cadmium oxide, and 0 to 5 wt.% an oxide additive selected from the group consisting of aluminum oxide, zinc oxide, and cadmium oxide are dispersed in an organic vehicle to prepare a thick-film resistor composition, which is then printed on a substrate and fired, yielding a resistor for use in rheostats. |
