摘要

PROBLEM TO BE SOLVED: To provide a composition for a thick film resistor capable of suppressing the generation of voids between the electrode and the thick film resistor when a thick film resistor is produced on the electrode. A composition for a thick film resistor. The composition for a thick film resistor includes a conductive powder containing silver particles having an average particle size of 0.5 μm or more and 7.0 μm or less, and palladium particles. Aluminoborosilicate glass having a softening point of 750 ° C. or higher and 900 ° C. or lower and containing at least one selected from CaO, MgO, and BaO. The palladium particles include a first particle having an average particle size of 0.05 μm or more and 0.15 μm or less, and a second particle having an average particle size of 0.25 μm or more and 0.55 μm or less. The conductive powder is a composition for a thick film resistor containing the silver particles in a proportion of 44% by mass or more and 48% by mass or less when the total content of the silver particles and the palladium particles is 100% by mass. Provide things. [Selection diagram] Fig. 1
