A capacitor 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. An insulation resin case is formed on the projected portion so as to surround the capacitor by a molding process using an epoxy resin. An insulation cylinder with an upper portion inserted in the recess also can be molded simultaneously with the insulation resin case. Since in replacement of an insulating case and/or insulating cylinder of a conventional capacitor, an insulation resin structure is formed by a molding process, the number of elements is reduced and the assembling process for attaching these elements is eliminated to thereby improve the productivity. Further, since the holes for fastening a ground fitment are not required, the noise can be effectively shielded.
