摘要：
A rubber composition that can obtain a rubber elastic body having small rolling resistance and excellent impact resilience and a method for producing the same, and a tire having small rolling resistance and excellent impact resilience are provided.The rubber composition of the present invention is obtained by kneading a rubber component containing a conjugated diene polymer (A) having at least one functional group selected from a tertiary amino group, a thiol group, a hydroxyl group, an epoxy group, a carboxylic acid group, a thioepoxy group, a hydrocarbylthio group and a hydrocarbylsilyl group and a conjugated diene polymer (B) having no functional group chemically bondable to silica, silica (C) and a dispersing agent (D) composed of an organic compound having at least one element selected from the group consisting of nitrogen, carbonyl oxygen and ether oxygen.
