Deflection coil and manufacturing method therefor.

摘要

A deflection coil includes a bobbin (10) made of insulating material and having a coil guide portion (10a), and a coil assembly (40) made by winding a coil wire (20) around the coil guide portion and fixing the coil wire to the coil guide portion. In a manufacturing method for such a deflection coil, the coil wire is wound around the coil guide portion by repeating the operation including moving a coil wire supply member (50) from the bobbin front end to the rear end, turning the bobbin by a predetermined angle, returning the supply member to the front end, and reversely turning the bobbin by the same angle as the predetermined angle.
