Abstract
A magnetron includes an anode cylindrical body, a plurality of vanes, a cathode filament, an input-side magnetic pole, an output-side magnetic pole, and a choke structure. The anode cylindrical body has a cylindrical shape with an input-side opening part and an output-side opening part. The plurality of vanes is radially disposed from a central axis of the anode cylindrical body to an inner wall surface of the anode cylindrical body. The cathode filament is disposed along the central axis of the anode cylindrical body. The input-side magnetic pole and the output-side magnetic pole are disposed on the input-side opening part and the output-side opening part, respectively. The choke structure is seamlessly formed and disposed so as to cover an opening rim of the input-side magnetic pole with respect to the central axis of the anode cylindrical body.
