A carbon black is disclosed which can exert excellent abrasion resistance while suppressing heat generation when incorporated into a rubber composition. A carbon black in which the total number of active sites represented by a product of a full width at half maximum of a Raman scattering peak appearing in a range of 1340 to 1360 cm−1 when an excitation wavelength is 532 nm and a specific surface area when nitrogen gas is adsorbed is 3.60×104 to 8.20×104 (cm−1·m2/g), and when a nuclear magnetic resonance signal of a spin-spin relaxation process observed by a solid echo method is represented by a sum of a first signal and a second signal having a time constant larger than that of the first signal, an amount of hydrogen represented by a signal intensity per unit mass at time 0 of the first signal is 50.0 to 250.0 (/g).
