To provide a high-damping laminate which is high in damping performance and excellent in shearing modulus as well, to provide a rubber composition for the high-damping laminate, capable of obtaining the laminate and excellent in processability, and to provide carbon black to be used in the rubber composition.

There is provided the carbon black having the following characteristics: the nitrogen adsorption specific surface area is 150-250 m2/g; the difference between the nitrogen adsorption specific surface area and CTAB adsorption ratio surface area is ≤25 m2/g; and the ratio of the half-width (D50) of the aggregate distribution to Stokes diameter(Dst):[(D50)/(Dst)] is ≤0.62.
