Abstract: A method of manufacturing a stator that includes a tubular-shaped stator core and a tubular-shaped coil. The method includes: (a) a holding step of holding an insulation sheet, which is disposed in a slot provided in the stator core, by causing a pressing device to press the insulation sheet against an inner surface of the slot in an axial end potion of the stator core; (b) an inserting step of inserting a segment portion of the coil to an inside of the insulation sheet from a side of the axial end potion of the stator core, in a position distant from the pressing device that presses the insulation sheet against the inner surface of the slot; and (c) a retracting step of retracting the pressing device by extracting the pressing device from the slot, after the inserting step. Also disclosed is an apparatus for manufacturing the stator.
