Abstract: An antenna part of a magnetron includes an exhaust portion that is connected to an antenna conductor derived from an anode part and has an output terminal from which a microwave is outputted, and an output-side ceramic stem that holds internally the antenna conductor and is firmly fixed to the exhaust portion to insulate electrically a side pipe connected to the anode part of a main body of the magnetron from the exhaust portion. An antenna part further includes an antenna cap that is joined to the exhaust portion by a conductive adhesive arranged on an outer periphery of the exhaust portion. Accordingly, it is possible to provide the magnetron that can prevent occurrence of electric discharge between the antenna cap and the exhaust portion.

Abstract: A magnetron includes a cooling block having an annular continuous portion with opposite end portions opposed to each other, the cooling block being secured to an outer peripheral surface of the cylindrical anode body, the cooling block having a coolant circulation pathway defined therein, a tightening member engageable with the opposite end portions of the cooling block to tighten the cooling block by reducing a distance between the opposite end portions of the cooling block, and a pair of pipe joints each connected to a portion of the cooling block adjacent to one of the opposite end portions so as to communicate with the coolant circulation pathway. The tightening member is disposed between connecting portions of the pair of pipe joints with the cooling block so as to extend in a direction inclined with respect to a plane including an annular direction of the cooling block.
