    Abstract: A steel cord that is especially useful for reinforcing a crown portion of a tire is provided. In particular, a steel cord free from manufacturing problems existed in the conventional art and allowing for stable quality and good production efficiency is provided, and a rubber-steel cord composite and a tire that are equipped with the same are provided.
    A steel cord has a multiple-twist structure including N (N = 2 to 8) strands 2 that are twisted together, each strand 2 having a plurality of wires 1 that are twisted together. When the diameter of each strand is denoted by d (mm), the diameter of a circle circumscribing the cord is denoted by D (mm), and the twisting pitch of the cord is denoted by P (mm), ε c defined by the following expression, ε c = √(-b/2 + √(b 2 /4 - c)) - 1 (where b denotes -1+π 2 (-4R 2 +d 2 )/P 2 , c denotes π 2 d 2 k(4π 2 R 2 +P 2 )/P 4 , R denotes (D-d)/2, and k denotes tan 2 (π/2-π/N) satisfies ε c ≥0.005.
