PROBLEM TO BE SOLVED: To provide a method for efficiently producing a carbonic microsphere having optically anisotropic structure. SOLUTION: This method for producing a carbonic microsphere comprises a step for mixing an optically isotropic pitch with an optically anisotropic pitch in a weight ratio of (1:0.1) to (1:1.5), a step for stirring the mixture, if necessary by adding carbon black, at 250-400 deg.C and a step for forming and separating a carbonic microsphere consisting essentially of the optically anisotropic structure to provide the carbonic microsphere (having 0.01-500μm particle diameter). The carbonrc microsphere is, if necessary, treated in an oxidative atmosphere for thermal stabilization and thereafter fired and/or grafitized. |
