PURPOSE:To facilitate manufacture by flanging the end part of a sensor head to which a sensor chip for temperature detection and a sensor metallic fixture are fixed, and joining the flange fixedly to the flange at the end part of a cylindrical case. CONSTITUTION:The sensor chip 6 is fixed to a sensor head 15 with a joint layer 7. The sensor chip 6 consists of an insulating substrate 3, electrode film 4, and temperature sensing resistor film 5. Further, the sensor metallic fixture 9 is fixed to the sensor head 15. An insulating plate 8 is fitted to the sensor metallic fixture 9. A groove or hole 12 for guiding a sensor lead wire 11 is provided to the insulating plate 8. The sensor head 5 is provided with a flange, which is joined with the flange of a cylindrical case 16. The sensor head 15 is brought into contact with the bottom part of a cooking container 1 to detect the temperature. |
