description A method for manufacturing a stator, the method comprising a step of winding one conductive wire to produce unit coils (404), a step of forming a coil basket (406) having an inner diameter of a terminal or an anti-terminal side greater than an inner diameter of the anti-terminal side, resp. the terminal side, wherein each unit coil and the other unit coil overlap each other, a step of inserting, from the terminal side or the anti-terminal side of the coil basket (406), an inner core (302a) formed by a plurality of teeth (321) radially arranged at regular intervals along the circumferential direction and connection portions (321a) connecting radially-inner-side ends of the adjacent teeth, a coil basket contraction step of applying a force from an outer circumferential side to the coil basket (406) in which the inner core (302a) is inserted and a step of pressing, into an outer core (302b), the inner core (302a) to which the contracted coil basket (406) is mounted.
