Claim:
1. A rotary electric machine comprising: a stator having the stator core; a rotor; and a bobbin mounted to the stator core and configured to electrically insulate the stator core from a first coil wire to be wound around the bobbin, wherein the bobbin includes: wherein the terminal fixing portion includes a first groove set and a second groove set and the bobbin is configured to allow the first coil wire to be wound around the coil winding portion through the use of one of the first groove set and the second groove set, wherein the first groove set includes a first groove configured to guide a winding starting section extending from the winding starting end portion of the first coil wire to a winding starting position of the coil winding portion and a second groove configured to guide a winding finishing section extending from a winding finishing position of the coil winding portion to the winding finishing end portion of the first coil wire to intersect the winding starting section when seen in an axial direction, wherein the second groove set includes a third groove configured to guide the winding starting section and a fourth groove configured to guide the winding finishing section not to intersect the winding starting section when seen in the axial direction, wherein the rotary electric machine further comprises: wherein the additional bobbin includes an additional coil winding portion around which the second coil wire is wound and an additional terminal fixing portion to which a winding starting end portion and a winding finishing end portion of the second coil wire are fixed, wherein the additional bobbin body is configured such that, when seen in the axial direction, a winding starting section extending from the winding starting end portion of the second coil wire wound around the additional bobbin to a winding starting position of the additional coil winding portion does not intersect a winding finishing section extending from a winding finishing position of the additional coil winding portion to the winding finishing end portion of the second coil wire, and wherein the bobbin and the additional bobbin are disposed adjacent to each other in a circumferential direction of the stator.
