Abstract
Metal graphite material including a molded body having a collectivity of graphite particles and copper particles comprises graphite and copper as main elements, the copper particles including copper microparticles where each copper microparticle having average diameter between 5 and 100 nm contacts, and a cluster of the copper microparticles fixed on a surface of the graphite particle to form a conductive path of the contacting copper microparticles on the surface of the graphite particle, wherein a charge induced from the graphite particle is conducted, and a method for making metal graphite material comprises the steps of: applying a solution including metal complex whose main element is copper on a surface of a graphite particle and forming a coating film of the solution on the surface of the graphite particle, and calcinating a molded body of a collectivity of the graphite particles on which the coating films are formed under an oxygen including atmosphere, and heating the molded body under a deoxidizing atmosphere.
