To provide a stator, which is capable of substantially uniformly cooling an entire coil end portion, and capable of increasing the flow rate of a cooling medium flowing in a cooling path when increasing the supply amount of the cooling medium, thereby improving cooling efficiency. In the stator, a coil end portion 12 includes a plurality of axial conductor portions 13 provided continuously with slot conductor portions 11 that are respectively inserted in the plurality of slots 2, and respectively extend from the plurality of slots 2 outwards in an axial direction of the stator. The stator includes a cover member 20 including a main body portion 21 that covers at least an outer peripheral surface of the coil end portion 12 along an entire circumference, accommodating chambers 22 that are formed radially inside the main body portion 21 and individually accommodate the plurality of axial conductor portions 13, and an introducing path 23 for introducing a cooling medium into the accommodating chambers 22 . A gap between an inner wall surface of each accommodating chamber 22 and each axial conductor portion 13 serves as a cooling path in which the cooling medium introduced from the introducing path 23 flows. |
