An object of the present invention is to further improve upon the strength and durability of a wire rope. A wire rope has a core rope made of steel; a covering layer, which is made of a composite resin, covering the outer peripheral surface of the core rope; and multiple side strands, which are made of steel, wound on the outer peripheral surface of the core rope covered with the covering layer. The composite resin constituting the covering layer is obtained by blending cellulose nanofibers with polypropylene serving as a matrix.
