PURPOSE:To remove green drooping by providing, in a deflection yoke, a coil generating a six poles magnetic field by winding six sets of coils about a ring core, while making a part of the current of a vertical deflection coil to branch thereto. CONSTITUTION:The deflection yoke 4 of an inline type color cathode-ray tube having plural electron guns 3 arranged in an inline shape is provided with a coil 12 generating a six poles magnetic field inside a core 1 while winding six sets of coils 14 around a ring core 13 made of plastics of acryl resin. And a part of a current to be guided to flow through a vertical deflection coil is made to branch to said terminals 15 and 16. Accordingly, the sensitivity in the vertical direction of a green electron beam positioned in the center among three electron beams can be corrected from being more reduced due to its horizontal deflection, than the green and red electron beams positioned on both sides, while eliminating green drooping generated as the result of misconvergence.
