PROBLEM TO BE SOLVED: To provide a cable routing method at a deflecting portion, in a manner preventing a fretting phenomenon, deviation of a cable centroid from a design drawing centroid, and collapse of sheathes and synthetic resin films. SOLUTION: According to the cable routing method at the deflecting portion, a plurality of prestressing wires 6 each covered with a sheath 11 are penetrated through a through hole 5 formed in the deflecting portion 4 for deflecting the cable 1 arranged on an external surface of a structure, then they are held in the through hole 5 at intervals that do not bring the prestressing wires 6 into contact with each other, and a filler 14 is filled in the through hole 5, followed by straining the prestressing wires 6 after hardening of the filler 14. Alternatively, an inner pipe 15 may be set in the through hole 5 formed in the deflecting portion 4, and the plurality of prestressing wires 6 each covered with the sheath 11 are penetrated through the inner pipe 15. Then after arranging the prestressing wires 6 in the inner pipe 15 at intervals that do not bring the prestressing wires 6 into contact with each other, the filler 14 is filled in the inner pipe 15, followed by straining the prestressing wires 6 after hardening of the filler 14.
