Abstract
A PTC thermistor device includes a case in which a holding plate made of metallic material is vertically arranged; and on each of both main surfaces of the holding plate, an electrode from a respective one of two PTC thermistor units is fixed. Therefore, the two PTC thermistor units are thermally coupled with each other through the holding plate. A terminal is integrally formed at the lower end of the holding plate, which is exposed outside the case. A throughhole for reducing an area of a section of a heat conduction path from the holding plate to the terminal is formed in the heat conduction path.
