装置。[Claims for Utility Model Registration] (1) A positive temperature coefficient thermistor device including a positive temperature coefficient thermistor, an electrode terminal member, and a support member, wherein the positive coefficient thermistor has electrodes on opposing surfaces of a thermistor body. The thermistor element has an insulating gap on each of the both surfaces in which the electrode does not exist, and each of the insulating gaps is formed at a position facing the electrode on the opposing surface side. Each of the electrodes has an ohmic electrode that does not contain a silver component and a silver-based electrode portion that serves as an extraction electrode, and the ohmic electrode is connected to the thermistor element so as to define the insulating gap. The silver-based electrode portion is partially provided on the ohmic electrode at a position facing the insulating gap, and the electrode terminal member is formed on the silver-based electrode portion. The positive temperature coefficient thermistor is disposed so as to be in contact with the surface of the positive temperature coefficient thermistor and is attached to the support member, and the support member supports the positive temperature coefficient thermistor with the insulating gap or the silver-based electrode portion. Thermistor device. (2) The supporting member receives the positive temperature coefficient thermistor at one side of the positive temperature coefficient thermistor at the silver-based electrode portion and the insulating gap portion, and the electrode terminal member is a first electrode terminal member. and,
a second electrode terminal member, the first electrode terminal member being arranged to contact and press against the silver-based electrode portion facing the insulating gap received by the support member; , wherein the second electrode terminal member is disposed on the support member so as to contact the silver-based electrode portion received by the support member. The positive temperature coefficient thermistor device according to item 1.
