The device protects the high frequency leakage without high cost ferrite rubber, and reduces the manufacturing cost. The device includes a door (2) which open/closes the heating room, an internal plate (5) which forms the 1st capacitive seal between the front panel of heating room, an external plate (4) which adheres to the upper part in the internal plate, and holds the specified distance, a gap (5') which has the horizontal and vertical parts, a slot (5'b) which forms the constant distance in the lower horizontal part and vertical of gap (5'), and a choke cover (7) which covers an choke coil (6).
