The flange part has an outer surface positioned on a side opposite to the winding core part. The terminal fitting has a positioning part for positioning the wire and a weld bead formed as a result of welding between the terminal fitting and the end portion of the wire. The positioning part and weld bead are both positioned on the outer surface of the flange part. The weld bead has a protruding part that does not overlap the flange part.
