An object is to provide a rubber composition that is capable of significantly improving mechanical properties. Another object is to provide a rubber belt that has excellent mechanical properties. Provided are a rubber composition, and a rubber belt formed by using the rubber composition, which is incorporated with a rubber component containing an ethylene/α-olefin copolymer, and an organically treated clay mineral organically treated with an organic ammonium ion, wherein the ethylene content of the ethylene/α-olefin copolymer is in a range of 60-85% by mass, the rubber component has a Mooney viscosity of 10-55 at 125° C., and the organically treated clay mineral is incorporated in 6-30 parts by mass per 100 parts by mass of the rubber component.
