Abstract
To provide a thick film resistor paste for a resistor having no abnormalities of cracks in appearance and sufficient surge resistance, especially for low resistance, while using lead borosilicate glass, 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 a ruthenium-oxide-containing glass powder and an organic vehicle, the ruthenium-oxide-containing glass powder comprises 10 to 60 mass % of ruthenium oxide, a glass composition of the ruthenium-oxide-containing glass powder comprises 60 mass % or less 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.
