1. A winding structure for a rotating electric machine, comprising:
a core including a plurality of slots; and a coil including a first winding and a second winding combined by intersecting the first winding and the second winding with each other, the first winding and the second winding each comprising a pair of straight portions and a pair of coil end portions connecting the pair of straight portions, wherein: the pair of straight portions of the first winding and the pair of straight portions of the second winding are inserted into a same pair of slots among the plurality of slots so that the coil is assembled to the core; the coil end portions of the first winding and the second winding each comprise: a first crank-shape portion bending in a rotation axis direction of the rotating electric machine; and a second crank-shape portion bending in a radial direction of the rotating electric machine; and when viewing from the rotation axis direction, the first crank-shape portion of the first winding intersects with the second crank-shape portion of the second winding, and the second crank-shape portion of the first winding intersects with the first crank-shape portion of the second winding.
