ABSTRACT:
The present invention is a high frequency heating apparatus which has a high frequency oscillator for radiating high frequency energy when energized by a high voltage, a waveguide for propagating the high frequency energy from the high frequency oscillator to a heating cavity or heating chamber of the apparatus in which an object to be heated is placed, and an electric wave radiating member provided between and extending into the waveguide and the heating chamber. The electric wave radiating member both couples, through electric waves, the waveguide with the heating chamber and also radiates the high frequency energy into the heating chamber for uniform heat distribution within the heating chamber.
