The present invention provides a manufacturing method of a graphite material having small variation of a particle size and liftime. The manufacturing method of a graphite material comprises: a grinding process of grinding a carbon based raw material composed of a bonding agent and aggregate, and obtaining ground raw materials; a sorting process of sorting the ground raw materials at least to a first sorting raw material and a second sorting raw material, which the peak of the particle distribution thereof is larger than the first sorting raw material; and a mixing process of determining the mixture amount of the second sorting raw material based on the mass of the first sorting raw material so as to obtain forming materials. |
