    • PURPOSE: An electron beam focusing electrode and an electron gun using the same are provided to focus the electron to an anode direction separated from a cathode by passing the electron through the penetration hole of the electron beam focusing electrode. CONSTITUTION: A cross section of a second surface(32) of a penetration hole(33) emitting the electron is larger than the cross section of a first surface(31) of the penetration hole. The cross section of the penetration hole is inclined to the progressing direction of the electron beam passing through the inside of the penetration hole. A protrusion(34) is formed in at least one side of the penetration hole. The orbit of the electrons passing through the inside of the penetration hole is controlled by the protrusion. The distortion of the electric field is decreased in an edge part of the electron beam. The uniformity of the electron beam from the electron gun is improved.
