Provided is a rubber article-reinforcing steel cord having improved shear fatigue resistance while reducing the weight of the steel cord by using a wire of high tensile strength. The rubber article-reinforcing steel cord 10 is a steel cord 10 having a two-layer twisted structure comprising a core filament 11 composed of a plurality of filaments and a sheath filament 12 composed of a plurality of filaments twisted around the core filament 11, wherein the tensile strength of the core filament 11 is higher than the tensile strength of the sheath filament 12, and the core filament 11 and the sheath filament 12 are twisted together in the same direction and the same pitch.
