Claims

[Claims for Utility Model Registration] (1) A positive temperature coefficient thermistor device including a positive temperature coefficient thermistor, an insulating support member, and a power supply terminal, wherein the positive temperature coefficient thermistor has a plurality of through holes in its element body. and has electrodes on both opening surfaces, and a pair of the insulating support members are provided, each insulating support member having a through hole and a recess around the through hole on the first side. The power supply terminal has a step part, and the power supply terminal is provided with a pair, each power supply terminal having a ring-shaped electrode contact part,
The electrode contact portions are individually assembled to each of the pair of insulating support members such that the electrode contact portions are located on the recessed step portions, and the pair of insulating support members are attached to the electrode contact portions of the power supply terminal. A positive temperature coefficient thermistor device, wherein the positive temperature coefficient thermistor is sandwiched between the positive temperature coefficient thermistor and the positive temperature coefficient thermistor is connected to the electrode of the positive temperature coefficient thermistor, and the positive temperature coefficient thermistor is connected to the electrode of the positive temperature coefficient thermistor. (2) Each of the pair of insulating supports has a recessed step on each opposite end side, and the pair of power supply terminals are arranged in opposite directions. It has two terminal parts led out, and is assembled to each of the pair of insulating supports such that the two terminal parts are led out to the surface of the recessed step part of the insulating support. In the pair of insulating supports, a protrusion is formed at one end from which one of the power supply terminals is led out, and a groove corresponding to the protrusion is formed at the other end from which the other power supply terminal is led out. A positive temperature coefficient thermistor device according to claim 1, characterized in that the positive temperature coefficient thermistor device is combined in such a manner that
