Original Abstract Submitted

A stator for a rotating electric machine includes: a stator core provided with slots arranged in a circumferential direction such that the slots are formed in two or more layers in a radial direction; and coils each having an inserted portion positioned inside the slots, and terminal end portions protruding from one end side and another end side of the stator core in an axial direction; wherein the coils include first coils formed to have a straight-line shape at their terminal end portions, second coils inclined in the circumferential direction at a predetermined angle with respect to an end face of the stator core at the one end side or the other end side of the terminal end portions, and third coils inclined in the circumferential direction at a predetermined angle with respect to the end face of the stator core at the one end side and the other end side of the terminal end portions, and the first coils, the second coils, and the third coils are connected to each other at their respective end portions to form a multiple winding.
