Thick film resistor paste, thick film resistor, and electronic component

A thick film resistor paste containing a ruthenium-oxide-containing glass powder, characterized by comprising:

• a silver powder or a palladium powder, or a mixture of both of the silver powder and the palladium powder;
• a ruthenium-oxide-containing glass powder;
• and
• an organic vehicle,
• wherein the thick film resistor paste comprises 11.2 mass % or more and 16.8 mass % or less of the ruthenium oxide contained in the ruthenium oxide-containing glass powder relative to 100 mass % of the thick-film resistor paste composition containing the ruthenium oxide-containing glass powder;
• wherein the ruthenium-oxide-containing glass comprises 40 mass % or more and 60 mass % or less of the ruthenium oxide;
• wherein a glass composition of the ruthenium-oxide-containing glass comprises 33 mass % or more and 60 mass % or less of silicon oxide, 30 mass % or more and 48 mass % or less of lead oxide, and 5 mass % or more and 50 mass % or less of boron oxide relative to 100 mass % of glass components;
• and
• wherein a combined amount of silicon oxide, lead oxide and boron oxide in the ruthenium-oxide-containing glass by mass % is 81.9 mass % or more and 95 mass % or less relative to 100 mass % of the glass components.
