Abstract
A magnetron includes semi-circularly shaped electric field adjusting grooves provided on surfaces of outer ends of vanes brought into contact with an inner surface of a positive polar body to make distribution of an electric field uniform on the surfaces of the outer ends of the vanes. Accordingly, the electric field becomes uniform by the electric field adjusting grooves provided on the surfaces of the outer ends of the vanes, so that generation of undesirable harmonics is suppressed.
