Abstract: An anode cylinder and a permanent magnet are efficiently cooled, and a cooling member per se is prevented from being upsized while suppressing a variation of a cooling performance for the permanent magnet. A magnetron according to the present invention includes: an anode cylinder; permanent magnets disposed on both ends of the anode cylinder; a magnetic yoke which stores the anode cylinder and the permanent magnets therein; a cooling member which stores the anode cylinder therein and which has at least a part thereof fixed to the anode cylinder; and a connection portion arranged between the magnetic yoke and the cooling member.

Abstract: A magnetron 1 according to the invention is equipped with an anode cylinder 112 having a high-frequency wave output unit 111, permanent magnets 122 disposed on the two respective sides of the anode cylinder, and magnetic yokes 121 which house the anode cylinder and the permanent magnets inside. One, on the high-frequency wave output side, of the magnetic yokes is formed with a plurality of cut and raised parts 1213. The anode cylinder and the one magnetic yoke are positioned with respect to the fixed to each other by sandwiching a metal plate 125 which matches the high-frequency wave output unit and the cut and raised parts 1213 between one of the permanent magnet and the magnetic yoke.
