To provide a steel cord for reinforcing rubber products having strong adhesiveness and capable of suppressing deterioration of vulcanized rubber and reduction of durability of a tire, and provide a method for producing the steel cord for reinforcing the rubber products.

The steel cord for reinforcing the rubber products is produced by intertwisting several filaments. As the filament, a brass-plated steel wire 13 adhered with cobalt on its surface is used. The brass-plated steel wire is adhered with the cobalt just after wire drawing in a cobalt-adding oil treatment process by using an oiling device 20, which process is arranged after a wire drawing process by using a final dies 14Z in the wet wire drawing by using multiple step type wet wire drawing equipment 10.
