Abstract
A suspension body for an elevator includes a core having a belt-like shape, and a covering layer covering at least a part of an outer periphery of the core. The core includes a load bearing layer. The load bearing layer is formed of an impregnation resin and a plurality of high-strength fibers. Further, the load bearing layer is divided into a plurality of segment layers arranged apart from each other in a thickness direction of the core. An intermediate layer made of a material different from that for the load bearing layer is interposed between the segment layers adjacent to each other in the thickness direction of the core.
