A microwave oven door, and more particularly, an apparatus for shielding electromagnetic wave that compensates for the length of slots formed in an end of an oven door in order to improve the shielding ability capable of preventing the leakage of electromagnetic wave from the cavity. In the apparatus, a choke structure includes a choke base connected with an inner portion of the oven door, a choke inner side portion bent perpendicularly from the choke base and a choke top bent from the choke inner side portion to contact a front circumferential portion of an oven cavity. Slots are formed in the choke top and the choke inner side portion at a predetermined interval. Each slot is extended from a distal end of the choke top to a predetermined point of the choke inner side portion. The predetermined point is distanced the same as or smaller than the half of the width of the choke inner side portion from a joint between the choke top and the choke inner side portion.
