An induction heating circuit includes an electrically conductive heating element (92) for generating heat using an induction heating method, an induction coil (91) configured to generate a magnetic field for induction heating, a driving signal generation unit (20, 112) configured to determine a frequency of a driving signal for driving the induction coil (91) with a driving signal and to generate the driving signal which becomes equal to or higher than a set minimum frequency, a current detection unit (110) configured to detect a current corresponding to electric power supplied to the induction coil (91), and a control unit (10) configured to, if the frequency of the driving signal is the minimum frequency and the detected current is equal to or less than a predetermined value, generate a signal representing abnormality of the supplied electric power. |
