PROBLEM TO BE SOLVED: To reduce the deformation of the coil end of a full coil caused by a centrifugal force, and to make the full coil adaptable to even a high-speed large-capacity machine. SOLUTION: A rotor coil 6 composed of the full coil continuously wound with conductors is inserted into a slot 2a of a core 2 fixed to a rotating shaft 5. At the coil end 16 of the rotor coil 6, a bind layer 8 formed by being wound with a resin-impregnated high-rigidity fiber material all over the whole external periphery of the coil end 16, and a metal ring 9 is fitted to the external periphery of the bind layer 8.
