PURPOSE: A deflection yoke is provided to effectively prevent the noise generated during the operation of a precise convergence correction unit, from being transferred to the entire part of deflection yoke through the circuit board. CONSTITUTION: A deflection yoke comprises a coil separator(21) having a neck part and a screen part, and a horizontal deflection coil arranged along the inner periphery of the coil separator; a circuit board(30) attached to the outer surface of the neck part of the coil separator, and which has a terminal for supplying power to horizontal and vertical deflection coils; a precise convergence correction unit(40) having a case(41) coupled to the circuit board, and a core(43) wound with a coil(42) and accommodated into the case; and a noise cut-off member arranged between the case of the precise convergence correction unit and the front surface of the circuit board, and which prevents noise generated during operation of the precise convergence correction unit from being transferred to the circuit board.
