PROBLEM TO BE SOLVED: To provide a method for producing a carbon fiber cord for reinforcing rubber having excellent adhesiveness in the interface between the carbon fiber cord and a substrate consisting essentially of rubber, excellent fatigue resistance and further excellent tensile characteristics (tensile modulus). SOLUTION: This is carried out by treating a substantially zero-twist carbon fiber bundle with a resin composition containing an acid-modified styrenic thermoplastic elastomer resin, providing a zero-twist yarn, single-twisting the one yarn or doubling the plurality of yarns and then single-twisting the doubled yarn at a twist multiplier within the range of≥1.5 to≤3.5. Furthermore, the yarn is preferably treated with a resorcin-formalin-latex-based adhesive composition after applying the twists. A styrenic thermoplastic elastomer resin is preferably a maleic acid-modified styrenic thermoplastic elastomer resin and the styrenic thermoplastic elastomer resin is preferably a styrene-terminated ethylene-butylene copolymer resin.
