A heating apparatus includes a heating element having a conductor, at least a part of which is an electrically closed circuit along which an eddy current flows; a container for accommodating the heating element; a magnetic field induction section for induction-heating the heating element; and a high frequency power supply device for supplying high frequency power to the magnetic field induction section. The heating element is induction-heated by an AC magnetic field generated by the magnetic field induction section.
