Abstract:
1. A process for producing a graphite particle having an average particle diameter of 5 to 50 μm, wherein ten or more recesses having a depth of 0.5 to 10 μm are formed in the surface by ten or more recess-forming particles pushed into each AB plane of graphite crystal to deform, the diameter of each recess being ⅕ to ⅓ of the particle diameter of said graphite particle, which method comprises: mixing raw material graphite particles and recess-forming particles, press-molding the mixture composed of the raw material graphite particles and the recess-forming particles to obtain a molded article, pulverizing the molded article, and separating and removing the recess-forming particles from the pulverized molded article to obtain said graphite particle.
