A magnetron includes an anode cylinder (1), a plurality of vanes (2) attached to the inside of the cylinder, a cylindrical metallic container (15), an output-side insulating tube (16), an antenna conductor (11), and a choke body (21). A hollow cylindrical metallic container (15) forms an airtight space at one end of the anode cylinder (1) and one end of a hollow output-side insulating tube (16) is airtightly connected to the container (15). An antenna conductor (11) electrically coupled with one of the vanes (2) extends through the cylindrical metallic container (15) and the output-side insulating tube (16). One end of a choke body (21) of a length of 1/4 wavelength of a harmonic to be suppressed is electrically coupled with the cylindrical metallic container (15), and its other end. The choke body is an annular groove type (21) or of a coaxial type (31).

A microstripline for use in a microwave heating comprising conductors each provided over both surfaces of a dielectric base plate. A plurality of slits are arranged distributed in the propagating direction of a microwave on at least one conductor, thereby to form a ladder portion. At least one conductor having the ladder pattern is sandwiched by a silicone resin.
