PURPOSE:To prevent a thermistor from jumping or being broken even though a vibration is applied thereto by fixing the thermistor and an insulating pipe to each other by a heat resisting cement. CONSTITUTION:A pair of the lead-out wires 12 of a thermistor 10 are welded to lead wires 14, which are passed through a two-holed insulating pipe 16 and the pipe 16 and the thermistor 10 are fixed to each other by using a heat resisting cement 18. Further, the cement 18 is filled in the holes of the insulating pipe 16 to fix the wires 14 to the insulating pipe 16. The insulating pipe 16 is fixed to a metal pipe 20 by using a heat resisting cement 22. The metal pipe 20 is connected to a fixing metal 26 and a gasket 28 is mounted to the metal 26. The lead wires 14 are connected to sensor output takeout wires 30 which are stranded wires and passed through an auxiliary ring 32 made of silicone rubber. The ring 32 is fitted in the metal pipe 20 and caulked by a caulking portion 34 to be fixed to the metal pipe 20, constituting a temperature sensor S.
