Provided is a rubber composition having excellent adhesiveness to a metal member even if no cobalt salt is contained. The rubber composition contains a rubber component, a rubber-metal adhesion promoter containing Bi, and an organic acid salt of metal other than Bi, where a content of metal element other than Bi with respect to a content of Bi element (content of metal element other than Bi/content of Bi element) in the rubber composition is more than 14 and 100 or less in terms of molar ratio, a content of the rubber-metal adhesion promoter is more than 1.5 parts by mass with respect to 100 parts by mass of the rubber component, and the amount of substance of metal element other than Bi contained in the organic acid salt of metal other than Bi in the rubber composition is 0.01 mol or more.
