Abstract: Granular acetylene black excellent in dispersibility in rubber, plastic, and the like and conductivity-endowing effect and scarce in dust scattering. The granular acetylene black is made from acetylene black wherein the half-width of the 1355 cm.sup.-1 band in the Raman spectrum is 55 cm.sup.-1 or less and the amount of iodine adsorbed is 95 mg/g or more. The method for making the granular acetylene black comprises granulating the above acetylene black using ion exchange water as a wetting agent, drying the granulated acetylene black at temperatures below 300.degree. C., and selecting particles whose hardness is less than 5 g/particle.
