Abstract
PURPOSE:To suppress the heating of a cross arm by forming the cross arm of a deflection yoke with a specific character of material. CONSTITUTION:In an in-line type color picture tube, a cross arm 34 to form a correction magnetic field on a fluorescent screen 4 side of a deflection yoke 30 by combining with the leakage magnetic field of a vertical deflection coil magnetically is furnished on the deflection yoke 30 which scans on the fluorescent screen 4 by deflecting three electron beams. By forming the arm with a high resistance and high permeability material of a specific resistance 10<2>OMEGA.cm or more, and the specific permeability 50 or more, the generation of an eddy current by the magnetic field of a horizontal deflection yoke of the cross arm can be eliminated almost perfectly. As a result, the heating of the cross arm is suppressed and a color picture tube of a good picture quality can be produced.
