摘要:
A polygonal coil having a substantially square shape is manufactured by winding a conductive wire in the diameter direction of the core on the core in an overlapping manner by the use of a winding jig in which a first collar portion and a second collar portion are disposed at both ends of a core so as to be opposed to each other and four rod-shaped protrusions are disposed on a surface of the first collar portion opposed to the second collar portion so as to protrude in a radial shape centered on an end of the core,. As a result, it is possible to obtain a polygonal coil with high precision.
