摘要： When an inverter circuit is driven at a predetermined driving frequency, an amount of current change per predetermined period of time of an input current or a coil current is detected, and a heating period from a start of control until the amount of current change becomes a set value or less is measured. Then, the inverter circuit is controlled to reduce high frequency power to be supplied to a heating coil in accordance with a length of the measured heating period.
