To provide an electromagnetic wave shielding device improved in shielding performance through length compensation of a slot, in particular, to shield an electromagnetic wave leaked from a cavity inside to its outside, in an oven door.
This electromagnetic wave shielding device of the present invention for the oven door includes a choke part provided with a choke bottom face connected to an inner side of a door, a choke inner face bent vertically from the choke bottom face, and a choke upper face bent from the choke inner face and contacting with a circumferential face of a cavity, and a slot part formed extendedly from the final end of the choke upper face up to a half or less of a length of the choke inner face, with a fixed space on the choke upper face and the choke inner face, in an electromagnetic wave shielding device for the oven door for shielding the electromagnetic wave having various forms of incident angles leaked from the cavity inside to its outside.
