The present invention provides carbon black, the standard deviation à of aggregate size distribution of which is obtained by a light scattering method using an ultraviolet ray, the standard deviation à satisfying the expression (1) : Ã< -48.7 × (24M4DBP/Dst) + 161.8 (1). In the expression (1), 24M4DBP represents the dibutyl phthalate absorption number (cm 3 /100 g) of compressed sample, and D st (nm) is a Stokes' equivalent diameter providing the mode in aggregate size distribution obtained by a centrifugal sedimentation method. The carbon black can improve both the abrasion resistance and the low rolling resistance of a tire. The present invention also provides a rubber composition mixed with this carbon black, and a pneumatic tire including a tread part formed by using this rubber composition.
