PROBLEM TO BE SOLVED: To provide a stator for a rotating electrical machine, which is downsized by reducing the outside diameter of a stator coil. SOLUTION: A stator 20 is provided with: an annular stator core 30 with a plurality of slots 31 in its circumferential direction; and a stator coil 40 constituted by wave-winding a plurality of lead wires 50 with slot-stored parts 41 to be stored in different slots 31 in its circumferential direction and turn parts 52 for connecting the fellow slot-stored parts 41 outside the slots 31 around the stator core 30. Each turn 52 part has the first and second crank parts 54a-54e, which are bent in the radial direction of the stator core 30, at its top 53, which is positioned farthest from the stator core 30. The second crank parts 54c and 54e (straight parts without bending) with bending amounts smaller than those of the first crank parts 54a, 54b, and 54d, are provided in a plurality of points in its circumferential direction.
