るカラー受像管。[Claims for Utility Model Registration] A phosphor screen formed on the inner surface of the face portion of an envelope consisting of a face portion, a funnel portion, and a neck portion, and a phosphor screen disposed within the neck portion that excites the phosphor screen to emit light. an electron gun structure that emits a plurality of electron beams; a substantially rectangular color selection electrode that is disposed in close opposition to the electron gun structure side of the phosphor screen and has a large number of electron beam passage holes; A magnetic shielding member is provided that is directly or indirectly stopped on the color selection electrode and extends along the inner surface of the funnel portion toward the electron gun structure, and is provided with an external device that finely adjusts the electron beam trajectory from outside the funnel portion. In a color picture tube using an additional magnet, the material of the magnetic shield is mainly Fe--Ni permalloy material, and the magnetic shield focuses the magnetic field from the external additional magnet to direct the electron beam to the electron beam. In positions where the trajectory can be fine-tuned,
A color picture tube characterized by partially using Fe material.
