PROBLEM TO BE SOLVED: To prevent the leakage of radio waves from a clearance part of a door by providing a salt water filled body absorbing the radio waves along the periphery of the door and the periphery of an opening of a heating chamber facing it.
SOLUTION: In a high frequency thermal cooker, a door 2 is mounted on the front of a heating chamber 1 and has a frame body 5 in the perimeter of a door plate 3. An annular tube 8 filled with salt water 7 is mounted inside the frame body 5 to form a salt water filled body. The tube 8 comprises an elastic material such as vinylchloride resin and is provided with an injection port and a drain port of the salt water 7. In this manner, as the circular tube 8 filled with the salt water 7 is provided inside the door 2, with the closing of the door 2, the salt water 7 is positioned at a possible clearance, the radio waves are absorbed by the salt water 7 thereby preventing the leakage of the radio waves from the clearance part of the door 2.
