ABSTRACT:
A magnetron for microwave ovens including a second insulator interposed between a connection part and a bottom of a yoke to form a relatively lengthened insulation distance, or a molded insulating plate attached to a bottom of the filter box to reduce a distance between the connection part and a bottom of the filter box. In the magnetron, an entire height of the magnetron is reduced, so that a miniaturization of the magnetron can be implemented and a design of a product including the magnetron, such as a microwave oven, can be freely carried out, thus allowing an appearance of the product to be variously designed.
