ABSTRACT:
An NTC thermistor element has a pair of outer electrodes formed on opposite outer end surfaces of a thermistor body made of an NTC thermistor material. A plurality of inner electrodes are formed inside this thermistor body in layers, each connected to either of this pair of outer electrodes. At least one of these layers contains a longer inner electrode and a shorter inner electrode disposed mutually opposite to each other, separated by a gap, and connected to different ones of this pair of outer electrodes. At least a portion of this longer electrode in this layer overlaps, in the perpendicular direction to the layers, another of the inner electrodes connected to the different outer electrode from the one to which this longer electrode is connected, with a thermistor layer in between.
