発明の名称 (英語) PTC THERMISTOR MEMBER AND PTC THERMISTOR ELEMENT コモンズ
発明の概要(英語) The purpose of the present invention is to provide a PTC thermistor member and a PTC thermistor element, each of which is provided with a large PTC effect and current conduction durability. A PTC thermistor element (1) comprises a PTC thermistor member (2) and electrodes (3a, 3b). The PTC thermistor member (2) comprises a matrix and conductive particles that are dispersed all over the matrix. The matrix contains an electrically insulating inorganic material. The inorganic material undergoes a phase transition of the crystal structure at a phase transition temperature, while undergoing a volume change. The conductive particles comprise first conductive particles and second conductive particles that are formed from a material different from the material of the first conductive particles. The first conductive particles are composed of particles having a melting point of 1,550°C or more. The second conductive particles are composed of a metal boride, a metal silicide, a metal carbide or particles having a melting point of less than 1,550°C.
