PROBLEM TO BE SOLVED: To provide an induction heating cooker preventing failure of cooking and securing safety by enabling to heat a non-magnetic load at a normal heating mode, and preventing to continue the cooking when the non-magnetic load or floating of a load is generated at a deep-fried food cooking mode, namely a temperature control heating mode, regardless of the kind of the load. SOLUTION: The induction heating cooker is composed of an inverter means 4 supplying high frequency current to a heating coil 5 and a resonance capacitor 6, a load judging means 9, a temperature sensing means 8, a switching means 7 switching resonant states, a control means 10 controlling the above, and the temperature control heating mode depending at least on the normal heating mode and temperature setting by a user. A state of the load 13 is judged by the load judging means 9, and a transition to the temperature control heating mode is prevented by the switching means 7 when it is set to at least one resonant state out of the resonant states of the heating coil 5 and the resonant capacitor 6.
