PROBLEM TO BE SOLVED: To enable to efficiently supply power to an induction heating coil through a non-contact power supply unit in a simple circuit configuration. SOLUTION: The apparatus is provided with a primary side unit 2 and a secondary side unit 3, and the primary side unit 2 is provided with a primary coil 6 and an inverter 20 for supplying an AC electricity to the primary coil 6, and the secondary side unit 3 is provided with a heating body 12, an induction heating coil 11 for induction-heating the heating body 12, and a secondary coil 7 which contacts with the induction heating coil 11 and moreover makes transformer coupling with the primary coil 6 in non-contact, and in the primary side unit 2, a capacitor 13 resonating with the primary coil 6 is connected with the primary coil 6 to form a primary side resonance circuit 4, and in the secondary side unit 3, capacitors C2, C3 are connected in series and/or in parallel with the secondary coil 7 and the induction heating coil 11 connected in series to form a secondary side resonance circuit 5 having the same resonance frequency in each of the couplings of the secondary coil 7 and the capacitor C2, and the induction heating coil 11 and the capacitor C3.
