It is to provide a high-elasticity rubber composition having a good workability while preventing the deterioration of rubber properties and capable of reducing rubber burning as far as possible by using a vulcanization accelerator having a retarding effect equal to or more than that of DCBS without using a retarder such as CTP possibly causing the deterioration of rubber properties after the vulcanization and problems such as blooming and the like and capable of realizing a higher elasticity and excellent low heat-buildup. The rubber composition according to the invention is characterized by comprising a rubber component, a sulfenamide-based vulcanization accelerator represented by a formula (I), a bismaleimide derivative represented by a formula (II) and sulfur.
