PROBLEM TO BE SOLVED: To reduce the manufacturing cost by enhancing the material efficiency of strap rings. SOLUTION: A magnetron is characterized in that in the cuts of the sides 21b, 21c to a plurality of planar veins extending from an anode cylinder 14, a large diameter strap ring 26 and a small diameter strap ring 27, short-circuiting the vein alternately, are arranged. Inside diameter of the large diameter strap ring is equal to the outside diameter of the small diameter strap ring, and the strap rings are arranged with a step so as not to come into contact with each other.
