Abstract
A collector core of a microwave tube has an insulator and a radiator around a cylindrical outer peripheral portion thereof. The cylindrical insulator and radiator comprise a slit along a central axis of the collector core, respectively. These slits are arranged on mutually overlapped positions. Portions of the collector core corresponding to these slits are cut off so as to be flat or concave. These slits and the flat surface or the concave portion are arranged symmetrically in a section of the collector core.
