ン管。[Scope of Claim for Utility Model Registration] The vacuum envelope consists of a panel part, a funnel part, and a neck part, and a black conductive film with a wide area and a fluorescent film with a narrow area are sequentially formed on the inner surface of the panel part, and furthermore, this fluorescent film is formed on the inner surface of the panel part. In a color cathode ray tube in which a shadow mask is disposed opposite to a light film and is fixed to a cross-sectional frame, a part of the frame is extended to form the outermost edge of the black conductive film and the outermost edge of the fluorescent film. A color cathode ray tube, characterized in that the shadow mask is protruded toward the screen side of the panel with respect to a straight line connecting the outer edge thereof, and the shadow mask is fixed to the inner surface of the frame.
