摘要： A fiber cord for reinforcement has an adhesive treatment agent attached to a surface thereof and includes, in an inner layer part thereof, two kinds of compounds each having a molecular weight of less than 1,000. The main compound is an aromatic compound or contains an α-dicarboxylic acid component, and the other compound is an aliphatic compound or an alicyclic compound. It is preferable that the adhesive treatment agent is a resorcin-formalin-latex-based adhesive, that the fiber cord includes a twisted synthetic fiber, that the aromatic compound is a heterocyclic compound, that the main compound is located only in the inner layer part of the fiber cord, that a compound having a hexamethylene diisocyanate trimer structure is present, and that no latex is present in the inner layer part of the fiber cord. This fiber cord is produced through a two-stage treatment with a pre-treatment liquid and adhesive treatment liquid.
