Abstract

PURPOSE:A positive characteristic themistor with high voltage-withstand, in which a gradient is given to the impurity concentration of a BaTiO3 system positive characteristic thermistor element so that temperature resistance becomes higher toward the inside, thus assuring high resistance to a large current.
