Beschreibung
Zusammenfassung:	Provided is a stator (2) including a coil (40) of a winding of a flat wire conductor (41), a stator core (10) including a slot (23) for housing a part of the coil (40), and a flow passage part through which a coolant (C) flows, provided between a wall part of the slot (23) and an outer surface of the coil (40) facing the wall part. The extension shape of the flow passage part from an inlet to an outlet for the coolant (C) changes along the axial direction of the stator core (10). The flow passage part is, for example, a concave part (24) formed on the wall part of the slot (23).
