A rubber composition includes at least one rubber component selected from the group consisting of natural rubbers and synthetic rubbers, a graphitized carbon material, and a polycyclic aromatic compound having a crosslinking group. The graphitized carbon material is preferably vapor-grown carbon fiber. The content of the graphitized carbon material is preferably 0.1 to 100 parts by mass based on 100 parts by mass of the rubber component.
