Provided is a steel cord for reinforcing a rubber article. Applied to a tire, the steel cord can produce greater increases in cut resistance. The steel cord for reinforcing a rubber article comprises one core strand (11) that has a layered twisted structure that is formed by twisting together a plurality of steel filaments (1), and comprises a plurality of sheath strands (12) that have a layered twisted structure that is formed by twisting together a plurality of steel filaments (2), the sheath strands being twisted together around the core strand. The ratio (S1/S) of the sum (S1) of the cross-sectional areas of outermost layer sheath filaments that constitute an outermost layer sheath of the core strand to the sum (S) of the cross-sectional areas of all of the filaments that constitute the core strand is 0.69-0.74, and the ratio (Ps/P) of the sum (Ps) of the strengths of the sheath strands to the total strength (P) of the cord is 0.81-0.85.
