To provide a highly reliable composite fiber cord for reinforcing rubber, which has tensile strength, extensibility under low load, high elastic modulus and adhesiveness under high load of a composite fiber cord, retains the tensile strength during use in long period of time.SOLUTION: A composite fiber cord for reinforcing rubber is a composite fiber cord including composite fibers consisting of a fiber bundle A formed of aromatic polyamide fibers and a fiber bundle B formed of low elastic modulus fibers, and a resin adhesive adhered to the composite fibers. Single fiber fineness of the aromatic polyamide fiber is 0.5 to 1.5 dtex.SELECTED DRAWING: None
