Abstract
This rotating electric machine rotor has a rotor coil composed of; a lower coil field wound around the outer circumference of a winding drum portion of a bobbin; and a mountain-wound coil field wound around the outer circumference of the lower coil field. A cross point in the mountain-wound coil field and a cross point in the lower coil field are shifted from each other in the circumferential direction. Thus, it becomes possible to shift the cross point positions without changing the thickness of the winding drum portion of the bobbin and without using a tape or the like.
