This reinforcement cord comprises at least one strand. The strand comprises: a bundle of a plurality of filaments that are bundled together and twisted in one direction; and a coating film that is formed on at least the surface of the bundle. The bundle is substantially configured of carbon fiber filaments. The coating film is formed from an aqueous treatment agent that contains a rubber latex and a crosslinking agent as essential ingredient, while containing a filler as an optional ingredient. With respect to the aqueous treatment agent, the total of the mass of the crosslinking agent and the mass of the filler is within 1-50% of the mass of the rubber in the rubber latex. La présente invention concerne un cordon de renfort qui comprend au moins un brin. Le brin comprend : un faisceau d'une pluralité de filaments qui sont groupés et tordus dans une direction ; et un film de revêtement qui est formé sur au moins la surface du faisceau. Le faisceau est sensiblement conçu de filaments de fibre de carbone. Le film de revêtement est formé à partir d'un agent de traitement aqueux qui contient un latex en caoutchouc et un agent de réticulation en tant qu'ingrédient essentiel, et une charge en tant qu'ingrédient facultatif. Par rapport à l'agent de traitement aqueux, le total de la masse de l'agent de réticulation et de la masse de la charge est au sein de 1 à 50 % de la masse du caoutchouc dans le latex en caoutchouc.
