An induction heated cooking apparatus for heating a removable cooking vessel having one of high resistance and a low resistance. The apparatus includes a power source for supplying a power source voltage, an induction heating device responsive to the power source for inducing an eddy current in the cooking vessel, including an induction coil device for exposing the vessel to a magnetic field for inducing the eddy current and a device for generating a high frequency current for inducing the magnetic field, an impedance state detection circuit for detecting the high frequency current, a frequency state detection circuit for detecting the frequency of the high frequency current and a control circuit for controlling the induction heating device in response to the impedance state detection circuit and the frequency state detection circuit.
