Disclosed is a rubber-reinforcing cord (10) containing reinforcing fibers (11). The surface of each reinforcing fiber (11) is provided with a coating film (12). The coating film (12) mainly contains a rubber which includes acrylonitrile as one of the raw materials, and a compound containing an oxazoline group. Also disclosed is a method for manufacturing a rubber- reinforcing cord which comprises a step (i) wherein an aqueous mixture mainly containing a rubber latex, which includes acrylonitrile as one of the raw materials, and a compound containing an oxazoline group is applied to reinforcing fibers, and a step (ii) wherein a coating film is formed on the surface of each reinforcing fiber by drying the aqueous mixture applied to the reinforcing fibers.
