A deflection yoke is constructed of a truncated conical hollow core, a pair of saddle-shaped horizontal deflection coils disposed inside the core, and a pair of toroidal vertical deflection coils wound on the core or a pair of vertical deflection coils wound in a saddle-like configuration and arranged in the vicinity of the core. A pair of cancellation coils opposing each other on an imaginary axis which passes through a central axis of the core in the direction of vertical deflection are arranged near front end sections of the vertical deflection coils, respectively. A central axis of each of said cancellation coils is inclined at a predetermined angle relative to the central axis of the core. The cancellation coils are connected with the horizontal deflection coils, respectively.
