A microwave leakage shielding device for a microwave oven includes a seal plate integrally formed with a slit and having a bent surface disposed at a flange by coupling of the flange and the bent surface of the seal plate for obtaining a first shielding effect, a tuning post member having a certain period based on a TE mode wherein there exists no electric field in the direction of the wave direction for obtaining a second shielding effect, a choke seal disposed in the damping groove for obtaining a third shielding effect, and a capacitive seal formed by coupling of the bent surface of the door frame and the flange for obtaining a fourth shielding effect, whereby the microwave leakage shielding device exhibits an excellent shielding capability and is convenient in assembling with the microwave oven.
