Abstract
A deflection yoke includes ferrite core, horizontal deflection coil, vertical deflection coil, and insulating frame for insulating the horizontal and vertical deflection coils. The deflection yoke has a cross section that satisfies the following A to C. A: A plurality of magnetic substance convex portions projecting toward the tube axis are provided in the vicinity of a position of an inner surface of the ferrite core where a vertical axis crosses. B: Assuming that a minimum value among distances between the respective magnetic substance convex portions and a funnel is D, the distance between the ferrite core excluding the plurality of magnetic substance convex portions and the funnel is larger than the distance Dat any point of the ferrite core. C: A part of the vertical deflection coil is wound in a groove between the plurality of magnetic substance convex portions.
