摘要： A curved metal plate is adhered to an outer surface of a cylindrical jig of the same shape, the metal plate is cut along the spiral coil winding pattern, the unnecessary metal portion other than the coil winding is peeled off from the jig to leave only the coil winding on the jig, an adhesive is applied on the coil winding, and an insulating sheet is covered over the jig (the coil winding thereon). After the coil winding is adhered to the insulating sheet, the insulating sheet (together with the coil winding) is peeled off from the jig. As a result, a saddle coil adhering the spiral coil winding to the inner side of the curved cylindrical insulating sheet is manufactured. According to such manufacturing method, without requiring huge equipment such as drying furnace, the saddle coil having a desired winding pattern with high precision can be manufactured in a short time and at low cost.
