    Abstract: A steel cord used to reinforce a tire according to the present invention includes a lower edge and an upper edge surrounding the outer peripheral surface of the lower edge to form m + n structures. The lower edge includes multiple cores extending in parallel without being twisted together. Each of the cores includes a flat surface in the intersecting area and the cores are in surface contact with each other through the flat surface.

    Abstract: PROBLEM TO BE SOLVED: To provide a steel wire of a flat cross-sectional shape with excellent flexural fatigue strength than conventional one for reinforcing a rubber article and to provide a rubber article including the same.SOLUTION: The steel wire for reinforcing a rubber article 10 has a width direction cross section with a major axis and a minor axis, the major axis and the minor axis being substantially perpendicular to each other. When the major axis is denoted by W, the minor axis by T, a line passing through the center in the width direction of the major axis and parallel to the minor axis by L1, a line passing through the center in the width direction of the minor axis and parallel to the major axis by L2, an intersection point of L1 and L2 by a central point C, an area within half the distance from the central point C to a surface by a center area Rc, and an outer area of the center area Rc by a surface layer area Rs, the Vickers hardness Hvc of the center area Rc is greater than the Vickers hardness Hvs of the surface layer area Rs. Also, when the Vickers hardness on L1 in the surface layer area is denoted by Hv1 and the Vickers hardness on L2 in the surface layer area Rs by Hv2, the relation represented by Hvc-Hv1≤150Hvc-Hv2≤150 is satisfied.
