Claims

[Scope of utility model registration request]

(1) A ceramic stem is protruded from one end of the anode cylinder via a metal cylindrical sealing body, and further supports the cathode located along the axis of the anode cylinder and has a lead for power supply. In the magnetron, a pair of cathode support rods, which also serve as a cathode support rod, are hermetically fixed to the ceramic stem, - a pair of cylindrical card terminals, at least one of which has a cylindrical flange portion, are hermetically connected to the ceramic stem; A magnetron characterized in that the cathode support rod is inserted into one end of a terminal and hermetically sealed, and an external lead is inserted into the other end and electrically connected.

(2) The magnetron according to claim 1, wherein the airtight joint portion of the pair of lead terminals is the outer surface of the ceramic stem.

(3) The magnetron according to claim 1, wherein the air volume joint of at least one of the pair of lead terminals is on the inner surface of the ceramic stem.
