PROBLEM TO BE SOLVED: To provide polyphase corrugate winding for electric rotating machine, capable of reducing the space of a coil end part and the loss of resistance power. SOLUTION: A front end 222 of a cross conductor 22 is radially displaced by the roughly radial thickness or larger of the crossover conductor by a step- difference 223, so that only by storing the respective phases of coils 2a, 2b, 2c manufactured by press molding into a slot, winding can be almost finished and be much more simplified than in a conventional complex winding process, which had been conducted using a winding machine or manually. The three- dimensional shapes of the respective crossover conductors 22 are made roughly equal, as compared with the curved-molding of the cross conductor of the conventional coil conductor, and since a coil end can be manufactured by sequentially shifting circumferentially the respective conductors 22 plastically deformed into the identical shape, it is possible to significantly miniaturize (particularly downsizing in the radial direction) the coil end than the conventional one, and eliminate the loss of resistance power caused by wasteful wiring extension of the crossover conductors 22.
