PROBLEM TO BE SOLVED: To provide a heating report device which is simple in structure, cheap, and capable of detecting whether heating is carried out or not. SOLUTION: A heating report device is composed of a thick film thermoelement 1, an LED 2, an electric contact 4 which interlocks with a turn-on/off switch 4, and a lead wire 3. The thick film thermoelement 1 is composed of a board 10 of 2.0mm or below in thickness and pairs of P-type and N-type thick film thermoelectric materials 30 which are connected together by the ends, baked on the board 10, and 0.01mm or above in thickness. When the tip of the thick film thermoelement 1 is heated, the LED 2 starts emitting light, and when heating is stopped, the LED 2 is also turned OFF at the same time, so that it is detected whether heating is carried out or not. |
