Abstract: In this winding structure for a rectangular wire, a coil is formed that is provided with: a core that forms a core main body; a teeth portion that is formed extending inwards in a radial direction from the core; and a jaw portion that is formed extending in a circumferential direction from a distal end on the inner side in the radial direction of the teeth portion, and in which a rectangular wire is wound in multiple layers around a slot that is formed surrounded by the teeth portion, the core, and the jaw portion. The ellipticity, which is a ratio of a width dimension relative to a thickness dimension of a cross-section of the rectangular wire, becomes larger as it is wound from inner layers of the coil towards outer layers thereof, and the ellipticity of the rectangular wire in each of the layers is set in accordance with the width dimension of the slot in each layer of the coil such that the generation of gaps between the slot and the rectangular wire is suppressed.
