Abstract
A coil includes first and second coil elements both of which are formed by feeding one piece of a rectangular wire rod by a predetermined amount and winding rectangularly in an edgewise manner using winding heads, the first and second coil elements being wound in opposite directions from each other. A winding terminating end point of the first coil element is bent approximately 90 degrees in a direction opposite to a winding direction of the first coil element, and is connected to a winding terminating end point of the second coil element in a same flat plane. The second coil element includes an offset portion of the rectangular wire rod that is offset in a plan view from a side of the second coil element.
