    Abstract: PROBLEM TO BE SOLVED: To provide a rubber article-reinforcing steel cord capable of sustaining stable performances, such as resistance to propagation of corrosion, in a longitudinal direction of the cord as well, without causing decrease in production efficiency, nor increase in weight, and to provide a pneumatic tire to which the rubber article-reinforcing steel cord is applied.
    SOLUTION: This rubber article-reinforcing steel cord 1 has a double twisted structure formed by twisting two or more strands each comprising two or more steel element wires, wherein each of the strands 2 is formed by twisting a core 5 which is formed by twisting two of the steel element wires 3 and a sheath 6 which comprises the steel element wires 4 twisted around the core 5, a circumscribing circle formed by a circumscribing circle of the core 5 and steel element wires 4 of the sheath 6 has an approximately elliptical shape, and a relation between a major axis A and a minor axis B of the elliptical shape is expressed by formula: 0.70≤B/A≤0.77.
