Abstract
A conductor wire material CW is wound into an accurate size without causing floating and deformation when an electric coil is formed. When the conductor wire material CW supplied from a wire material feed portion is wound by turning a coil-winding mold and is processed to fabricate an electric coil having a desired coil shape, the coil-winding mold is linearly moved in a direction D away from the wire material feed portion by a distance corresponding to a major side portion to impart predetermined tension to the conductor wire material CW when a winding portion of the coil-winding mold on which the conductor wire material is wound is the major side portion and the coil-winding mold is rotated when the winding portion of the coil-winding mold on which the conductor wire material is wound is a minor side portion
