ABSTRACT:
In a positive temperature coefficient thermistor, a terminal holding member is provided between an outer casing and an elastic terminal electrically connected to the semiconductor ceramic element. The terminal holding member is formed of a thermoplastic resin having a low softening point. Consequently, when an abnormally large amount of heat is generated in the semiconductor ceramic element, the terminal holding member melts and deforms, causing the semiconductor ceramic element to be separated and thereby electrically disconnected from the terminal.
