PROBLEM TO BE SOLVED: To provide a steel cord excellent in impact resistance.SOLUTION: The steel cord has a 1×n structure formed by twisting n (n=3 or 4) wires. In a cross section perpendicular to a longer direction, when an area of a circumscribed circle is defined as S1 and an area of a wire is defined as S2, a void ratio V represented by the following formula (A) is 37% or higher and 60% or lower. V(%)=(S1-nS2)/S1×100...(A)SELECTED DRAWING: Figure 2
