Abstract (en)
An induction heating cooking apparatus according to the present invention obtains an amount of temporal change ”l of at least one of an input current to a drive circuit 50 and a coil current flowing through a heating coil 11 a, in a state where a drive frequency of the drive circuit 50 is fixed, measures a heating time t1 from start of power supply to the heating coil 11 a until the amount of temporal change ”l becomes equal to or less than a set value, and controls high-frequency power supplied to the heating coil 11 a depending on the heating time t1 and an amount of current change l1 of at least one of the input current and the coil current during the heating time t1.
