It has front and rear coil sides formed along the front and rear crossover wires of the horizontal deflection coil, and generates a magnetic field to cancel the leakage magnetic field generated from the crossover wire when horizontal deflection current is applied. 1. A deflection yoke comprising: a canceling coil that generates electricity; and a magnetic shielding body that covers a straight portion between a front coil side and a rear coil side of the canceling coil.
