PROBLEM TO BE SOLVED: To reduce costs and make electric appliances compact with a power supply shared between them, by controlling the state of an output of the inductively heated power supply by using outputs from state-detecting elements and performing the control so that at least two electric appliances can be used at the same time. SOLUTION: High-frequency current from a power supply 1 for induction heating is supplied to heating coils 4, 5 of inductively heated electric appliances 2, 3 at the same time, high-frequency magnetic fields generated by the heating coils 4, 5 each interlink a heat generating body, and the heat generating body is induction-heated by an eddy current generated therein. A control part 8 controls an output of the power supply 1 for induction heating by using outputs from state-detecting elements 6, 7 present in the inductively heated electric appliances 2, 3, and prevents an abnormal rise of temperature in the event of temperature adjustment or no-load heating. Priorities are assigned to the induction-heating type electric appliances 2, 3 by the use of a selector switch 10 or the like, and the output of the power supply 1 for induction heating can be selectively controlled by using the outputs from the state-detecting elements 6, 7 on the basis of the priorities.
