ABSTRACT:
A magnetron10is equipped with a helical filament39, as an element of a cathode assembly, arranged on a central axis of an anode cylindrical body13. Assuming that a resistance value of the filament39before forming the carbonized layer is R1and a resistance value of the filament39after forming the carbonized layer is R2, a thickness of the carbonized layer42of the filament39is determined such that a carbonization rate Rx defined by the equation “Rx={(R2−R1)/R1}×100” in a range of from 30 to 50%.
