Summary:PROBLEM TO BE SOLVED: To provide a thick-film thermistor composition which has a simple structure and of which thermistor characterisitic does not change by surge current resulting from static electricity, and which is superior in stability and durability; and to provide its manufacturing method and a thick-film thermistor element. SOLUTION: The thick-film thermistor is made mainly of a thermistor oxide that is a semiconductor ceramics made of transition metal oxide and is comprised of polycrystal with spinel structure crystal grains, conductor components such as RuO2or the like and a binder glass, and it contains 5-15 mass% of an oxide of Pr as a rare earth element to total inorganic component amount. The thermistor oxide powder is obtained by dissolving its material in an oxalic acid water solution at a specified mix proportion, coprecipitating, temporarily baking, and crushing it.
