    c is defined by the following formula, wherein d(mm) expresses the diameter of the strand, D(mm) expresses the diameter of a circumscribed circle of the cord and P(mm) expresses a twisting pitch: ε
    c =√(-b/2+√(b
    2 /4-c))-1 [wherein b expresses -1+π

    SOLUTION: The steel cord 1 has a 3×3 structure prepared by laying 3 strands 2 obtained by laying 3 wires 3 without a core strand. The external tangent line S2 of the strands 2 is a nearly elliptical shape in nearly the same direction in the longitudinal direction and the external tangent line S1 of the steel cord 1 is a nearly elliptical shape in nearly the same direction as the elliptical direction of the strands 2. The flatness (b2/a2) of the strands 2 is 1.15-2.70 and the flatness (b1/a1) of the steel cord 1 is 1.15-2.70. Furthermore, the adjacent strands repeat contact or approach and separation at least twice in one lay pitch and the maximum gap when separated is present near the extreme points of the major axis.
