A rubber composition comprises: a rubber component; 0.01 parts by mass or more of a rubber-metal adhesion promoter per 100 parts by mass of the rubber component, the rubber-metal adhesion promoter containing at least one selected from the group consisting of a carboxylic acid metal salt (1) having a carbon number of 2 to 25 and a metal species selected from the group consisting of bismuth, copper, antimony, silver, niobium, and zirconium and a compound (2) represented by formula (A); and 4,4'-diphenylmethanebismaleimide. The use of the rubber composition enables obtainment of vulcanized rubber having good deterioration resistance, excellent durability, and excellent rubber-metal thermal deterioration adhesiveness.
