PROBLEM TO BE SOLVED: To provide a coating liquid for a rubber-reinforcing glass fiber, which establishes a coating layer on a glass fiber cord so that an EPDM rubber can be firmly attached to the glass fiber cord and that adhesive strength is not decreased by heat deterioration, and to impart flexibility to and increase flexibility in the rubber-reinforcing glass fiber on which the coating layer is established. SOLUTION: The coating liquid for the glass fiber is applied to the glass fiber cord, dried and cured to establish the coating layer for attaching an ethylene-α-olefin-diene ternary copolymer (EPDM rubber) to the glass fiber cord. The coating liquid for the glass fiber is obtained by mixing a water dispersion of resorcin-formaldehyde condensate and an ethylene-glycidyl methacrylate copolymer with a water dispersion of a styrene-butadiene copolymer.
