SOLUTION: The wire winder 1 is for winding a flat wire 60 on a salient pole 52 having partly bent cross-sectional shape. The wire winder is so constituted as to perform the following operation that it partly deforms a flat wire 60 by load rollers 11 and 12 so that the flat wire width is reduced in the axial direction of the winding. Thereafter, the flat wire 60 is wound so that the deformed portions of the flat wire 60 are abutted against corners of the salient pole 52, and underformed portions are abutted against straight portions of the salient pole 52.
