PROBLEM TO BE SOLVED: To obtain the subject composite wherein a spherical carbonaceous material having a particle size ofμm order or smaller, specifically 20 nm to 30μm in average particle size, and controlled in particle size distribution is homogeneously dispersed, and to provide a method for producing the above composite. SOLUTION: This method for producing a spherical carbonaceous material composite comprises the following consecutive processes: (1) a homogeneous mixed liquor composed of a phenolic resin, a cellulose derivative and a solvent is prepared, (2) the solvent is removed from the mixed liquor to cause the phase separation of the phenolic resin and the cellulose derivative, (3) the phenolic resin is cured to form a phenolic resin composite, (4) the phenolic resin composite is baked in an inert gas or vacuum atmosphere to obtain the objective spherical carbonaceous material composite 20 nm to 30μm in average particle size and pref. <=0.5 in the standard deviation of its particle size distribution.
