description In an induction heating apparatus, an infrared-ray detection portion (107) includes an infrared-ray reception portion (107a) adapted to receive infrared rays radiated from an object to be heated, an amplification portion (107b) adapted to amplify a detection signal from the infrared-ray reception portion to form an infrared-ray detection signal, and a temperature detection portion (107c) adapted to detect the temperature of the infrared-ray detection portion and to output the temperature to the control portion. The control portion (106) is adapted to correct the infrared-ray detection signal to form an infrared-ray real signal, when the temperature of the infrared-ray reception portion (107a) is equal to or higher than a temperature to be detected by the infrared-ray detection portion (107), based on information about a negative signal superimposed on the infrared-ray detection signal outputted from the infrared-ray detection portion (107), which is negative-signal information about the negative signal with the reverse polarity from that of the infrared-ray detection signal.
