Abstract
A method of producing a carbon-based material includes steps (a), (b) and (c). In the step (a), an elastomer and at least a first carbon material is mixed and the first carbon material is dispersed by applying a shear force to obtain a composite elastomer. In the step (b), the composite elastomer is heat-treated to vaporize the elastomer, and a second carbon material is obtained. In the step (c) the second carbon material is heat-treated together with a substance including an element Y to vaporize the substance including the element Y, a melting point of the element Y being low.
