PROBLEM TO BE SOLVED: To provide a rubber composition containing a rubber component consisting of a natural rubber and/or a synthetic diene rubber, especially a rubber composition giving a vulcanized rubber having low density and light weight after vulcanization. SOLUTION: The rubber composition having a density of 0.85-1.20 g/cm<SP>3</SP>after vulcanization is produced by compounding 100 pts.wt. of a rubber component consisting of a natural rubber and/or a synthetic diene rubber with 10-100 pts.wt. of a foamed ethylene-vinyl acetate copolymer having a density of 0.03-0.40 g/cm<SP>3</SP>and containing closed cells having a diameter of≤5 mm.
