    Abstract: PROBLEM TO BE SOLVED: To provide a steel cord for reinforcing a rubber product, used as a reinforcing material of the rubber product such as a tire for a vehicle and an industrial belt, and having an extremely flat shape and fatigue resistance.
    SOLUTION: The steel cord for reinforcing the rubber product, having a 3+N structure obtained by twisting N (N is 5-13) wires forming sheath side around a core consisting of three wires is regulated so that the core wires 11 may be parallel to each other, and arranged in one nearly linear direction at the cross section of the cord to form the cord cross section into the extremely flat shape, and the core wires 11 may satisfy the requirements in P of from 0.22Pc to 0.43Pc and in d1 of from 1.02d to 1.05d [wherein, P is the pitch (mm) of kink; Pc is a twisting pitch (mm) of the sheath wire; d1 is an apparent outer diameter (mm); and d is a diameter (mm) of the core wire] to facilitate the stretch of the core wire 11 and to enable a tensile load to be dispersed to the core wires 11 and the wires 12 at the sheath side.
