Abstract
A microwave sealing structure prevents leakage of microwave to the outside of the cavity in which microwave resonates, in an apparatus using microwave which includes a cavity in which an internal space is formed so that microwave can resonate having an opening, and a door for opening/closing the opening. In the structure, an equivalent impedance circuit, formed with a rim of the opening and a cross-section of the rim of the door to prevent leakage of microwave out of the cavity, is a LC resonant circuit.
