PURPOSE: A deflection yoke is provided, in which a magnetic piece made up of a material having high magnetic permeability is attached to the magnet for correction of screen distortion, to thereby prevent decrease of magnet force in the magnet. CONSTITUTION: A deflection yoke includes a magnet(20) arranged at a screen portion(11) of a coil separator(10) so as to correcting mis-convergence of the screen of CRT. The magnet has a correction piece(30) attached integrally with the magnet along the outer surface of the magnet corresponding to the screen portion of the coil separator. The correction piece has a high magnetic permeability, and maintains the magnet to generate magnetic force in a continuous and stable manner. The correction piece has a size and thickness smaller than those of the magnet.
