摘要： [Object] An object is to provide an induction heating method having a high power factor in which when thermal processing is performed through a plurality of heating coils receiving the supply of the current to generate mutual induction, it is possible to easily and rapidly perform synchronization control on a coil current and in which when the current is varied, even if the speed of control on the current value is increased, this little affects an inverter phase angle.[Solving means] In an induction heating method using an induction heating device that heats an item to be heated and includes a plurality of self-resonant circuits to which a resonant high-frequency power supply feeding currents of equal frequency to a plurality of heating coils receiving the supply of the current to generate mutual induction is connected, the phases of impedances within a system are made to coincide with each other to minimize the phases. From the time of starting up, the phase is made to become an inverter phase that can bring the phase difference of the currents close to zero. Control on the frequency and the current value is performed so that the inverter phase is controlled within a given range.
