Beschreibung
Zusammenfassung:	A compressed rubber layer of a V-ribbed belt includes a surface rubber layer including side surface portions of V-shaped ribs, and an inner rubber portion provided inside the surface rubber layer. The surface rubber layer and the inner rubber portion are each made of a rubber composition containing an ethylene-α-olefin elastomer as a main ingredient of a rubber component. An ethylene content of the ethylene-α-olefin elastomer contained in the rubber component of the rubber composition forming the surface rubber layer is higher than an ethylene content of the ethylene-α-olefin elastomer contained in the rubber component of the rubber composition forming the inner rubber portion.
