Claims

[Scope of utility model registration request]

(1) Through a metal cylindrical sealing body at one end of the anode cylinder,
A ceramic stem is protruded from the anode cylinder, and a pair of cathode supports that support a cathode located along the axis of the anode cylinder and also serve as power supply leads are hermetically fixed to the ceramic stem. In the magnetron, the ceramic stem has an integrally molded thin-walled cylindrical portion located inside the cylindrical sealing body, and an outer conductive layer is formed on the outer surface of the thin-walled cylindrical portion, and the ceramic stem has an integrally formed thin-walled cylindrical portion located inside the cylindrical sealing body. A magnetron characterized in that the thin cylindrical part is electrically connected to the cathode support, and an inner conductive layer is formed on the inner surface of the thin cylindrical part and electrically connected to the cathode support.

(2) The magnet 9 according to claim 1, wherein the length of the outer conductive layer is set to be approximately 174 times the wavelength of the second harmonic.
