Abstract
A PTC thermistor device has a PTC thermistor member and electrodes. The electrodes, are formed on respective surfaces of the PTC thermistor member. The PTC thermistor member contains a matrix phase, and conductive particles dispersed throughout the matrix phase. The matrix phase contains an electrically insulating first inorganic material and an electrically insulating second inorganic material. The first inorganic material undergoes phase transition in terms of crystal structure type and change in volume, at the phase transition temperature thereof. The second inorganic material is fibrous.
