Abstract:
1. A coil winding, comprising: a first winding part formed by winding a flat wire; a second winding part formed by winding the flat wire continuing to the first winding part, the second winding part being wound in a same winding direction as a winding direction of the first winding part; and a connecting wire part located between the first winding part and the second winding part to connect the winding parts, wherein the connecting wire part comprises: an interval defining portion defining an interval between the first winding part and the second winding part; a first coupling portion with one end side continuing to the interval defining portion by forming an edgewise bending and another end side continuing to the first winding part on one side in an axial direction of the first winding part; and a second coupling portion with one end side continuing to the interval defining portion by forming an edgewise bending and another end side continuing to the second winding part on another side in an axial direction of the second winding part, wherein the first coupling portion is continuing to the first winding part at the side opposite to the side facing the second winding part; and the second coupling portion is continuing to the second winding part at the side opposite to the side facing the first winding part.
