摘要:
A concentrated winding coil includes a plurality of coil layers each of which comprises a plurality of wire turns wound in alignment winding; and a bobbin including an inner flange, an outer flange and a bobbin body on which the wire is wound, wherein: each of the coil layers includes a turn shift portion where the wire is shifted from an n-th turn to an (n+1)-th turn; the turn shift portion is located only on a side of a coil end section of the coil; and the bobbin body has no guide grooves. A method of manufacturing the concentrated winding coil includes steps of: winding the wire on the bobbin; and pressing the wire by a wire guiding/holding member toward the inner flange or toward the outer flange.
