A temperature control device which can control the temperature of an object to be processed even after supply of radio waves or electromagnetic waves from a high-frequency heating apparatus is stopped. The temperature control device includes a temperature sensor detecting the temperature of the object to be processed heated by radio waves generated from the high-frequency heating apparatus, a signal processing circuit comparing the temperature detected by the temperature sensor with a standard temperature, a rechargeable battery charged by electric energy generated by reception of the radio waves by an antenna, a charging circuit controlling charging of the rechargeable battery, and a heater supplied with electric power from the rechargeable battery to heat the object to be processed so that the temperature thereof gets closer to the standard temperature, in accordance with a comparison result by the signal processing circuit.
