COMPOSITION FOR THICK FILM RESISTOR, THICK FILM RESISTANCE PASTE, AND THICK FILM RESISTOR

WIPO Patent Application WO/2019/059290

A1

[Problem] To provide: a composition for a thick film resistor having a high rate of decrease in resistance value as an amount of change in a resistance value that can be adjusted by an adjustment method using pulse trimming when forming a resistor; a thick film resistance paste; and a thick film resistor. [Solution] This composition for a thick film resistor contains ruthenium oxide-based conductive powder comprising mixed powder of ruthenium oxide and lead-ruthenium, and glass frit, and further contains silver powder of 16-33 mass%, wherein, when a thick film resistor is formed by sintering a thick film resistance paste to which an organic vehicle is added, the rate of decrease in resistance value of the thick film resistor, which can be adjusted by an adjustment method using pulse trimming, is set to be larger than 5%.
