Reference numeral 1 is an anode cylinder, 2 is a vane radially fixed to an inner wall of the anode cylinder, and 3 is a cathode assembly which is erected upright in the axial direction of the anode cylinder 1 close to the tip of the vane 2. Is a substantially cylindrical first and second sealing metal body with one end opening fixed to each end opening of the anode cylinder 1, and 6 is brazed to the other end opening of the first sealing metal body 4. The cylindrical insulator 7 is an exhaust pipe brazed and fixed to the cylindrical insulator, and the inside of the anode cylinder 1 is exhausted through the exhaust pipe. Then, the exhaust pipe 7 seals the tubular insulator 6 while holding the antenna conductor 8 extending from the vane 2. Reference numeral 9 denotes a bottomed tubular insulator that is brazed and fixed to seal the other end opening of the second sealing metal body 5.

However, the plating process may not be performed sufficiently. In this case, if rust occurs or corrosion occurs in the non-plated part, and if the brazing part with the tubular insulator 6 or the insulator 9 is not sufficiently plated, However, reliable brazing is not performed, and the yield in the manufacturing process is reduced.
