Abstract: A chip thermistor has a thermistor portion including a ceramic material containing respective metal oxides of Mn, Ni, and Co as major ingredients; a pair of composite portions including a composite material of Ag—Pd, and respective metal oxides of Mn, Ni, and Co and arranged on both sides of the thermistor portion so as to sandwich in the thermistor portion between the composite portions; and external electrodes connected to the pair of composite portions, respectively. In this manner, the pair of composite portions are used as bulk electrodes and, for this reason, the resistance of the chip thermistor can be adjusted mainly with consideration to the resistance in the thermistor portion without need for much consideration to the distance between the external electrodes and other factors.
