Abstract
To provide a thick film resistor paste for a resistor having a smaller resistance change rate and excellent surge resistance, a thick film resistor using the thick film resistor paste, and an electronic component provided with the thick film resistor. A thick film resistor paste comprises an organic vehicle and a conductive substance-containing glass powder comprising ruthenium oxide and lead ruthenate, the conductive substance-containing glass powder comprises 10 to 70 mass % of conductive substances, a glass composition of the conductive substance-containing glass powder comprises 3 to 30 mass % of silicon oxide. 30 to 90 mass % of lead oxide, 5 to 50 mass % of boron oxide relative to 100 mass % of glass components, and, a combined amount of silicon oxide, lead oxide and boron oxide by mass % is 50 mass % or more relative to 100 mass % of the glass components.
