Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rubber composition which has high performance and is excellent in processability, e.g. roll work, and a rubber product, e.g. a tire, which is reduced in rolling resistance and is excellent in fatigue and wear resistances.SOLUTION: A rubber composition is prepared by blending 100 pts.mass of a rubber ingredient with 30-80 pts.mass of carbon black whose DBP absorption amount and CTAB adsorption specific surface area meet expressions (I) to (III), and the macro-dispersion D(%) of the carbon black in the rubber composition is 1% or higher and lower than 10%. (I) DBP absorption amount(cm/100 g)
