度βとの間に、α〈γ〈β なる関係を満足することを特徴とするカラー受像管。[Claims for Utility Model Registration] An electronic system disposed within the neck of one end of the envelope;
a fluorescent surface provided on the inner surface of the panel portion at the other end of the envelope extending from the neck portion through the funnel portion; and a shadow mask disposed close to and opposite to the fluorescent surface and having a large number of openings. In the color picture tube, the shadow mask includes an effective part having a large number of holes, an intermediate connecting part extending in a peripheral direction of the effective part, and a skirt part extending from the intermediate connecting part. , the strength of the intermediate connection portion is weaker than that of the effective portion and the skirt portion, and the angle γ of the intermediate connection portion with respect to a plane perpendicular to the tube axis is an angle α of the connection of the shadow mask surface with respect to a plane perpendicular to the tube axis. 1. A color picture tube, characterized in that the orthogonal line between the electron beam irradiation angle and the angle β with respect to a plane perpendicular to the tube axis satisfies the relationship α<γ<β.
