Claims

[Scope of utility model registration request]

Two cylindrical cathode sleeves are arranged and fixed in parallel on a plane perpendicular to the electron gun axis, and the two cathode sleeves are arranged along the envelope top surface with the electron gun axis as the center. and a base metal body having an electron-emitting oxide layer formed on the surface thereof, the base metal body being fixed near the edge of each of the cathode sleeves, and the base metal body integrally extending from the center of the back surface thereof. A cathode assembly for an electron tube, characterized in that the cathode structure for an electron tube is provided with a plate-like body portion extending at right angles so as to be sandwiched between the two cathode sleeves.
