PROBLEM TO BE SOLVED: To improve manufacturing workability and enhance productivity. SOLUTION: A wire 1 is wound around from first end to an intermediate portion of the central side of a U-shaped core 4, the tap 3 of the wire is extracted from the intermediate portion, and a wire 2 is wound around from the intermediate portion to second end, thereafter, the wire is cut at the tap 3. The portion from the first end to the intermediate portion is assigned to first coil (a) and conducts a coma correction operation for the whole screen. The portion from the intermediate portion to the second end is assigned to second coil (b) and conducts a coma correction operation for the upper area or the lower area of the screen. Thereby, a cost can be reduced. |
