    Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a molding material and of a molding having both excellent conductivity and moldability (flowability, ease of molding, or the like upon molding). SOLUTION: The manufacturing method of the molding material comprises sticking a treating agent to a surface of a conductive material to obtain a composite conductive material, and mixing the composite conductive material with a resin, the resin being selected so that when the treating agent of 0.5-3 wt.% and the resin of 97-99.5 wt.% are mixed, they are not compatible with each other, and the resin has a nature in which the treating agent is coated by the resin to constitute a sea/an island structure. The manufacturing method of the molding comprises molding using the molding material.
