A stator includes: a plurality of divided cores disposed to have a ring shape; a stator winding toroidally wound on the stator; and a holding member that holds the divided cores in the ring shape. Each of the divided cores includes: a bobbin part for the stator winding; a yoke extending from the bobbin part in the circumferential direction; a connection part extending from the yoke outwardly in a radial direction with a connection face that is connected to the holding member; and a tooth extending from the yoke inwardly. The connection part has a magnetic gap to increase a magnetic resistance in a path of magnetic flux, generated by the stator winding, leaked to the holding member through the connection face. The magnetic gap is a notch or a weld.
