Abstract: A magnetron for holding deformation of a cathode side tube for alignment of a cathode filament and eliminating the need for alignment at the time of exterior assembly work of the magnetron is provided. The magnetron of the invention includes an anode cylinder; a cathode side tube hermetically coupled to a lower portion of the anode cylinder; and a shield cylinder having a cylindrical part extending in substantially a vertical direction, a flange part which is connected to the cylindrical part and extends in substantially a horizontal direction over the entire periphery of the cylindrical part, and a folded part in which a portion of the flange part is folded toward the cathode side tube, the shield cylinder being electrically coupled to the cathode side tube at a lower end of the anode cylinder.
