Abstract
A wire rope includes a strand that is formed by winding a plurality of metal wires. The strand includes a core wire and side wires. Each of the side wires is arranged on an outer periphery of the core wire. In a transverse section of the strand, each of the side wires includes end portions positioned at opposite ends in a circumferential direction of the core wire. Each of the end portions includes a contact portion in contact with an end portion of an adjacent side wire, and a non-contact portion not in contact with the adjacent side wire. A Vickers hardness of the contact portion is higher by 1% or more than a Vickers hardness of the non-contact portion. A surface roughness Ra of an outer peripheral surface of each of the side wires is 0.10 μm or less.
