Abstract
A method of manufacturing a carbon material that can prevent formation of unevenness of a coating film and degradation in adhesivity of the coating film, by inhibiting a carbon substrate from forming a portion in which a metal carbide layer is not formed. The method is characterized by including a first step of causing metal powder to adhere to a carbon substrate by coating the carbon substrate with a slurry containing the metal powder and polyvinyl alcohol as a binder, and a second step of heat-treating the carbon substrate to which the metal powder has adhered in a vessel containing an atmosphere of hydrogen chloride gas.
