The present invention provides a rubber composition for coating a steel cord, which has an excellent adhesion balance of initial adhesiveness, heat-resistant adhesiveness and moist heat-resistant adhesiveness and can improve oxidation deterioration resistance. SOLUTION: 100 to 100 parts by weight of a diene rubber, 30 to 80 parts by weight of carbon black, 0 to 15 parts by weight of silica, and 0.1 to 0.1 parts of phenolic resin or phenolic resin obtained by condensing a phenolic compound with formaldehyde. 10 parts by weight, 0.2 to 20 parts by weight of hexamethylenetetramine or melamine derivative as the methylene donor, 5 to 20 parts by weight of active zinc white having a nitrogen adsorption specific surface area of 20 m 2 / g or more by BET method, Is a rubber composition for coating a steel cord.
