A novel carbon black can improve rubber properties (e.g., degree of reinforcement and heat buildup). The carbon black has an aggregate void modal diameter Dmp determined by mercury porosimetry of 25 to 60 nm, and has a ratio (ΔDmp/modal diameter Dmp) of a half-width ΔDmp of an aggregate void diameter distribution determined by mercury porosimetry to the aggregate void modal diameter Dmp of 0.30 to 0.56.
