Claim:
1. A method of producing a composite conductive material, comprising a step of kneading at least a graphite-based carbon material and a conductive material into a base material, the graphite-based carbon material having, just before the kneading 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 P P implementation of the kneading step produces at least graphene exfoliated from the graphite-based carbon material, 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.
