(57) ABSTRACT
An insulator 6 for holding electrode wires 4 is provided between a thermistor element 3 and a sheathed pin 5 which is a wiring, and the electrode wires 4, which are inserted into hole portions 6a ol the insulator 6, are held therein not bonded to the insulator, whereby the vibration resistance ol the electrode wires ol the thermistor element is improved so that breaking ol the electrode wires is prevented.
