The rotation-resisting wire rope has a plurality of side strands. In side each strand, wires are laid in the same direction as the lay of core strand wires, around the periphery of a core strand. The side strands are laid in a direction opposite to the lay of the core strand wires so as to form the wire rope. The side strands preferably have a smaller pitch multiple than a pitch multiple of the wire rope. The ratio between a diameter of the side strands and a diameter of the core strand is preferably about 1.3 to about 1.8. The pitch multiple of strands is preferably about 5 to about 8 and the pitch multiple of the wire rope is preferably about 8 to about 10. Both the core strand and the side strands preferably have shaped wires, having a flattened surface, at an outermost ply.
