To provide a rubber composition that has sufficient low heat generation and excellent processability.SOLUTION: Provided is a rubber composition that contains the following components (a), (b) and (c). Component (a): a rubber component; Component (b): a compound represented by the following formula (1); Component (c): a compound represented by the following formula (2). (1) X-CO-NH-A (2) Z-CO-NH-A [In the formula, A indicates the group represented by the formula (i) -NR1R2 or the formula (ii) -N=R3R4, in formula (i) or (ii), R1 to R4 are hydrogen or an alkyl of 1 to 18 carbon atoms, X is a nitrogen-containing heterocyclic group, an alkyl of 1 to 5 carbon atoms, an aryl or a group -Y-CO-NHA, or may form a ring. Y is a divalent nitrogen-containing heterocyclic group, an alkylene of 1 to 18 carbon atoms, or an arylene, and Z is an alkyl of 6 to 40 carbon atoms.].SELECTED DRAWING: None
