An object of the present invention is to achieve both the processability of an unvulcanized rubber composition and the low exothermic improvement of a rubber composition after vulcanization. A rubber composition comprising a rubber component, silica, a silane coupling agent, and thiourea, wherein the blending mass ratio (thiourea / silane coupling agent) is (1/100) to (100 / 100).
