Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an adhesive rubber composition for steel cords remarkably improving adhesion (heat-resistant adhesion) after heat aging while maintaining the adhesion (initial adhesion) to the steel cords just after vulcanization. SOLUTION: The adhesive rubber composition for the steel cords is characterized in that sulfur and zinc white are compounded with a rubber component containing ≥50 mass% of natural rubber and/or synthetic polyisoprene rubber, the amount of the sulfur compounded is 5-8 pts. mass based on 100 pts. mass of the rubber component, and the mass ratio (zinc white/sulfur) of the zinc white to the sulfur is ≥2.2.
