PROBLEM TO BE SOLVED: To improve the bloom resistance of a high sulfur content rubber composition which has a sulfur content as high as, for example,≥3 pts.mass or, further,≥5 pts.mass of sulfur to 100 pts.mass of the rubber component without deteriorating other properties of the rubber. SOLUTION: The rubber composition contains 100 pts.mass of a diene-based rubber (A),≥3 pts.mass of sulfur (B) and 0.1-10 pts.mass of at least one kind of organosulfur compound (C) selected from the group consisting of compounds expressed by formula (I) or formula (II) (wherein, x is an integer of 1-10; n is an integer of 1-200).
