Abstract
A bobbin for electrically insulating the stator core from a coil wire to be wound around the bobbin includes: a coil winding portion around which the coil wire is to be wound; and a terminal fixing portion to which a winding starting end portion and a winding finishing end portion of the coil wire are to be fixed. The terminal fixing portion includes a first groove configured to guide a winding starting section extending from the winding starting end portion of the 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 coil wire to intersect the winding starting section when seen in an axial direction.
