Abstract
An NTC thermistor has an electrically insulating substrate, a temperature-sensitive film on a surface of the substrate containing oxide of rare earth elements such as LaCoO as its principal component by at least 50 weight %, and a pair of electrodes which are separated from each other and are each electrically connected to this film. An NTC thermistor chip is obtained by further forming a pair of outer electrodes which are each on a corresponding end portion and electrically connected to a corresponding one of the surface electrodes.
