    Abstract: A resonant circuit in an inverter includes a first resonant circuit configured with a heating coil and a first resonant capacitor connected in series to the heating coil, a second resonant circuit configured with the first resonant circuit and a second resonant capacitor connected in parallel to the first resonant circuit, and a resonance choke coil connected in series to the second resonant circuit. The resonant circuit is configured so that impedance of the heating coil and the first resonant capacitor is set to be close to impedance of the second resonant capacitor, at a frequency of a current flowing through the heating coil. Thus, an object to be heated can be efficiently induction-heated without an increase in a current flowing through the switching element.
