To provide a coil winding method which can wind a coil at high speed and improve a productivity.
The inside of a first flange in a coil winding area 14a of a first flange side 11 is set as a coil winding starting point 15, and a position apart from the first flange is set as a turning point 16. A coil 5 is wound on a winding shaft 13 on a outward trip from the coil winding starting point to the coil turning point to form a first layer 17 on the coil winding area, and returning at the coil turning point, a coil is wound on the coil of the first layer on a return trip toward the coil winding starting point to form a second layer 18. Returning at the coil winding starting point, a coil is again wound on the coil of the second layer on a return trip toward the coil turning point to form a third layer 19, and such a winding is repeated, then, a first winding layer 20 composed of a plurality of coil layers is formed on the coil winding area, and a coil is wound on a coil winding area 14b adjacent to the coil winding area formed of the first winding layer from the coil winding end of the first winding layer.
