ーミスタ装置。[Claims for Utility Model Registration] (1) A positive temperature coefficient thermistor device having electrodes on opposite surfaces of a thermistor element, wherein the thermistor element has an insulating gap on each of the opposite surfaces in which the electrodes are not present. Each of the insulating gaps is formed at a position facing the electrode on the other side, and each of the electrodes includes an ohmic electrode that does not contain a silver component and a silver-based electrode that serves as an extraction electrode. the ohmic electrode is formed on both sides of the thermistor element so as to define the insulating gap, and the silver-based electrode portion is on the ohmic electrode and is formed on the insulating gap. A positive temperature coefficient thermistor device characterized in that it is partially provided at a position facing a gap. (2) The thermistor body has a honeycomb shape having a large number of through holes penetrating in the direction of both surfaces, and at least one of the electrodes is covered with resin except for the silver-based electrode portion. The positive temperature coefficient thermistor device according to claim 1. (3) The positive temperature coefficient thermistor device according to claim 1 or 2, wherein the silver-based electrode portion is formed within the plane of the opposing insulating gap.
