PURPOSE:To enable a high quality picture characteristic to be obtained even in a fast scanning by forming so that a comatic aberration can be treated by a deflection york. CONSTITUTION:A pair of E-shaped magnetic substances 1 and 1' positioned at both left and right sides of electron beams R, G, and B in an in-line arrangement and a pair of U-shped magnetic substances 2 and 2' positioned at both upper and lower sides of electron beams R, G, and B are arranged. And auxiliary coils 3a, 3b, 3c, and 3a', 3b', 3c' are wrapped in each foot part of the pair of E-shaped magnetic substances 1 and 1', and auxiliary coils 4 and 4' in the middle part of the pair of U-shaped magnetic substances 2 and 2', these auxiliary coils 3a, 3b, 3c, and 3a', 3b', 3c', also 4 and 4' are connected each other in seres, and connected to a vertical deflection coil 9. A vertical deflection current is flowed to auxiliary coils 3a, 3b, 3c, and 3a', 3b', 3c', also 4 and 4' in such constitution. This enables a deflecting york to be used even in a high horizontal deflection frequency area.
