A deflection yoke includes horizontal deflection coils; vertical deflection coils; and coils for correcting a vertical pincushion distortion, which coils are provided aside from the vertical deflection coils; wherein the coils for correcting a vertical pincushion distortion have such a wire-wound form as to generate a magnetic field having a pattern substantially equal to that of the vertical deflection coils. This is effective to carry a parabolic current with horizontal cycles for correcting a vertical pincushion distortion at a low voltage, and hence to simplify the circuit configuration and reduce the manufacturing cost.
