摘要： Provided is a rubber composition comprising at least CR as a rubber component and having rubber-metal adhesiveness equal to or higher than that of a rubber composition comprising a cobalt salt. The rubber composition comprises a rubber component, and a rubber-metal adhesion promoter, where the rubber component comprises at least 10 parts by mass of CR per 100 parts by mass of the rubber component, the rubber-metal adhesion promoter comprises at least one selected from the group consisting of a metal salt of an aliphatic carboxylic acid (1) and a compound (2) having a specific structure.
