Abstract: A rotary electric machine includes a bus bar holder provided on one side of a stator in an axial direction, and a plurality of bus bar terminals that electrically connect the stator and a control unit. A lead wire is drawn out to a bus bar terminal side in an axial direction from a lead-out portion located on the bus bar terminal side among a plurality of windings provided all around a circumferential direction of the stator and between a plurality of adjacent windings. The bus bar terminal includes a winding side terminal portion having at least one connection part and a board side terminal portion connected to a board. The bus bar terminals are gathered in a part in the circumferential direction. The lead wire is wired so as to extend from one of the lead-out portions scattered all around the circumferential direction to one of the connection parts.
