PROBLEM TO BE SOLVED: To avoid the variations of a convergence characteristic and an image distortion characteristic by keeping the total current (coma correction current) flowing through a pair of correction coils at a certain level. SOLUTION: This deflection yoke is provided with a convergence correction circuit 19, having a pair of correction coils L1, L2 installed at positions opposite to each other by interposing the center axis of the deflection yoke at the rear end of the deflection yoke with their respective input terminals connected with each other, and a variable resistor VR1 of which one end and other end are connected the respective output ends of the pair of correction coils L1, L2, and connected in series with respect to vertical deflection coils Lv, Lv.
