Abstract:
A heating apparatus, comprising:a heating element having a conductor, at least 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; anda high frequency power supply device for supplying high frequency power to the magnetic field induction section,whwerein the heating element is induction-heated by an AC magnetic field generated by the magnetic field induction section;wherein the heating element is circumferentially wound around itself to form a cylindrical shape having two different points thereof electrically connected to each other by a connector so as to form the electrically closed circuit; andwherein overlapping parts of the conductor of the circumferentially wound heating element have a total thickness smaller than a skin depth of the conductor which is suitable for generating an electromotive force to cause the eddy current to flow in each of the overlapping parts along the closed circuit.
