構成されてなることを特徴とするマグネトロン。[Claims for Utility Model Registration] A metal container is hermetically connected to the open end of the anode cylinder either directly or through a pole piece, and a gasket contact ring that contacts the gasket and an insulating cylinder of the output part are airtightly connected to the end of the metal container. In a magnetron which is soldered and further includes a ring-shaped ferrite permanent magnet arranged around the metal container and the gasket contact ring, and a ferromagnetic yoke that is magnetically bonded to the permanent magnet and forms a magnetic circuit. An air guide slit is formed on the surface of the permanent magnet in contact with the yoke, and a ventilation hole is formed in the gasket contact ring, so that the cooling air that has passed through the air guide slit passes through the ventilation hole. A magnetron characterized in that the magnetron is configured to contact a soldered joint between the metal container and the insulating cylinder.
