A magnetron is disclosed in which the structure of the choke is altered, so that when designing the choke, the design allowance range is expanded so as to realize the optimum efficiency. Thus the unnecessary harmonic waves are more inhibited, and the coupling of the output part is improved owing to the impedance of the choke, thereby doubling the output and efficiency. The first choke includes: a first cylindrical body; a flange part extending from the top of the cylindrical body toward the anode seal; and a supporting means extending from the flange part toward the cylindrical body. The second choke includes: a cylindrical body; and a flange part extending from the top of the cylindrical body toward the anode seal. Thus the first and second chokes maintain a proper gap between them owing to the supporting means.
