Utilizing its elasticity, it is placed over the peripheral edge of the mounting hole in the side wall of the heating chamber, the flange of the insulating sleeve, and the part pressed by the elastic piece of the ground spring of the sheathed heater, and the ground spring is inserted through the conductive braided material. Since the tip of the elastic piece of the earth spring is pressed against the sheathed heater, it is possible to prevent a gap from forming between the elastic piece of the earth spring and the movable part of the sheathed heater, prevent leakage of radio waves from the heating chamber, and prevent the sheathed heater from forming a gap. The heater and the side wall of the heating chamber are directly connected by a conductive braided material, which more reliably prevents leakage of radio waves from the heating chamber via the sheathed heater.
