<p>Deflection yoke in a CRT including horizontal, and vertical deflection coils for deflecting the electron beams emitted from the electron gun in a horizontal, or vertical direction, a ferrite core (44) for reducing a loss of magnetic force caused by the horizontal, and vertical deflection coils (42) to enhance a magnetic efficiency, and a holder for holding the horizontal deflection coil, the vertical deflection coil, and the ferrite core at required positions, and insulating between the horizontal deflection coil and the vertical deflection coil, wherein the horizontal and/or vertical deflection coil has a substantially rectangular screen, and the ferrite core is circular or elliptical, thereby saving a material cost and improving convergence and distortion errors, because a dimensional distribution of an inside surface can be reduced and an inside surface polishing becomes easy, that improves a production yield and the dimensional distribution of the ferrite core, significantly. <IMAGE></p> |
