Abstract: In the winding wire at the winding completion end side, two wires are piled up vertically and wound together from the inner circumferential side towards the outer circumferential side. The winding wire at the winding start end side that has remained on the inner circumferential side is drawn forth from the inner circumferential side to the outer circumferential side so as to form a curve along the flat surface of the coil. In the crossing portions of the winding wire at the winding completion end side and the winding wire at the winding start end side, the two wires of each winding wire are superimposed and caused to cross each other in a state in which the wires are laid down transversely.
