Claim:
1. A method of producing a graphene composite, comprising a step of mixing at least a graphite-based carbon material in a base material, wherein graphene is partially exfoliated from the graphite-based carbon material and dispersed in the base material, the graphite-based carbon material having, just before the mixing step, a rhombohedral graphite layer (3R) and a hexagonal graphite layer (2H), wherein a Rate (3R) of the rhombohedral graphite layer (3R) and the hexagonal graphite layer (2H), based on an X-ray diffraction method, which is defined by following Equation 1, is 31% or more: wherein the graphene being a crystal of a mean size of 100 nm or more and formed in a flake-like or sheet-like shape having 10 layers or less.
