が同一平面上に組立てられた陰極線管用電子銃。An electron gun for a cathode ray tube comprising a cup-shaped first grid electrode having an electron beam passage hole on the bottom surface for controlling the electron beam emitted from the electron emitting surface of the cathode structure, and a main electron lens section for focusing the electron beam. , the plate thickness of the first grid electrode facing the electron emitting surface of the cathode structure near the electron beam passing hole is determined by a dimension corresponding to the desired distance between the first grid electrode and the electron emitting surface of the cathode structure. An electron gun for a cathode ray tube, in which the surface of the insulating base constituting the cathode structure that is in pressure contact with the inner end surface of the first grid electrode and the electron emission surface are assembled on the same plane.
