ABSTRACT:
A heating apparatus includes: an exciting coil provided in close vicinity of a heated body having a conductive layer; a capacitor connected serially or in parallel with the exciting coil; a switching element that generates a high frequency current by turning on/off a direct current and that supplies the high frequency current to the exciting coil and the capacitor; a specifying unit that specifies an electric value to be supplied to the exciting coil; an output unit that outputs, to the switching element, a driving signal to turn on the switching element for a period determined in correspondence with the specified electric value; a voltage detection unit that detects a flyback voltage value generated in a resonance circuit including the exciting coil and the capacitor; and an abnormality detection unit that detects an abnormality in the heated body based on the detected flyback voltage value.
