A stator manufacturing apparatus includes an insertion tool that is insertable into a stator core and being configured to dispose a pair of side parts of a stator coil in two holding grooves. A pressing tool has plate-like pushers arranged to correspond to the positions of the holding grooves. The pressing tool pushes out the side parts of the stator coils and inserts the side parts into the corresponding slots. A pair of shaping tools face coil end parts of the stator coils. A plurality of slits through which the pushers are insertable are provided in a principal surface of each shaping tool. A shaping tool moving unit shapes the coil end parts by pressing the pair of shaping tools in an axial direction with the pushers inserted in each of the corresponding holding grooves.
