Abstract: In an elevator rope, a plurality of steel outer layer strands are twisted together on an outer circumference of an inner layer rope. The inner layer rope has: a fiber core; a plurality of steel inner layer strands that are twisted together directly onto an outer circumference of the fiber core; and a resin inner layer rope coating body that is coated onto the outer circumference. A diameter of the inner layer strands is smaller than a diameter of the outer layer strands. The inner layer strands are greater in number than the outer layer strands.
