A noise shielding apparatus for the magnetron of a microwave oven is disclosed, in which the structure is relatively simple, so that the material cost would be saved, and that the productivity would be improved. An elliptic opening is formed on a side wall of a shielding case for installing a capacitor. The circumference of the opening is bent to form a projected portion for attaching a capacitor, and a recess is formed on the reverse side of the projected portion. Further, reinforcing ribs are formed around the projected portion of the shielding case. In the present invention, attaching a conventional separate ground fitment is unnecessary, so that the productivity would be improved. Further, since the holes for fastening the ground fitment are not required, the noise is not leaked through the holes.
