The present invention provides a rubber composition that is interposed between fibers and rubber and that can improve or improve the adhesion between the fibers and rubber. A rubber composition is composed of an ethylene-α-olefin-diene copolymer, silica, and a silane coupling agent. In such a rubber composition, the ethylene-α-olefin-diene copolymer contains 45 to 80% by weight of ethylene and 4 to 15% by weight of diene, and when measured at 125 ° C. according to JIS K6300-1, It may be an ethylene-α-olefin-diene copolymer having a Mooney viscosity of 30 to 120.
