を特徴とする陰極線管用電子銃。An electronic cathode ray tube comprising a triode section that generates an electron beam and forms an object point, and a focusing electrode section that includes at least two main focusing electrodes to which different potentials are applied to form a main focusing lens that focuses the electron beam. In the gun, two auxiliary electrodes are arranged between the main focusing electrodes to which the specific potential is applied, and of the main focusing electrodes, the two auxiliary electrodes are arranged on the side of the main focusing electrode to which a relatively high potential is applied. The auxiliary electrode is connected and supported so as to be at the same electric mark as the main focus electrode to which a relatively low potential is applied, and is disposed on the side of the main focus electrode to which a relatively low potential is applied. The auxiliary electrode is connected and supported so as to have the same potential as the main focusing electrode to which a relatively high potential is applied, and only the two main focusing electrodes to which different potentials are applied are a common insulating support. An electron gun for a cathode ray tube characterized by being supported.
