To provide a composite fiber cord for reinforcing rubber, which simultaneously satisfies the moldability of a rubber composition owing to elongation upon molding, required during molding processing of a rubber product, and stiffness desired in the cord when a rubber molded article is finally used.SOLUTION: A composite fiber cord for reinforcing rubber is a composite fiber cord which comprises a fiber bundle A comprising high-elastic-modulus fibers and a fiber bundle B comprising low-elastic-modulus fibers. The fiber bundle A is a plied fiber bundle which comprises two or more fiber bundles, and in which first twisting and second twisting are performed in opposite directions. The fiber bundle A and the fiber bundle B are both further subjected to second twisting in a direction opposite to the second twisting direction of the fiber bundle A. The composite fiber cord for reinforcing rubber contains a rubber component. Further, it is preferable that: the fiber bundle B is preliminarily subjected, before the second twisting, to first twisting in an opposite direction; and the high-elastic-modulus fiber is one fiber selected from the group of a glass fiber, aromatic polyamide fiber, carbon fiber, polyparaphenylene benzoxazole fiber, and aromatic polyester fiber.SELECTED DRAWING: None
