PROBLEM TO BE SOLVED: To perform high temperature display that notifies danger of a high temperature object by a non-electric source by using a thermoelectric conversion module. SOLUTION: One of the thermoelectric conversion module 17 is brought into close contact with a heat conduction unit 16b of a heat receiving plate 16 comprising a heat receiving unit 16a and the heat conduction unit 16b, and a heat sink 19 is brought into close contact with the other. The heat receiving unit 16a of the heat receiving plate 16 is arranged in a housing 11 having a heat generation source 12 with voltage applied thereto, and the heat conduction unit 16b is arranged outside the housing 11 through the housing 11. By this configuration, heat of the heat generation source 12 having high temperature is transferred to the thermoelectric conversion module 17 directly (without going through the surface of the housing 11) to increase difference of temperature and to increase electromotive force, which can operate a displaying means for displaying a high temperature state.
