摘要：
A method for producing a vitreous carbon material which can serve as a carbon material for a power storage device. In the method, a polymer material, having six-membered ring structures in its basic carbon skeleton and having a nitrogen atom, is heated at a temperature of 1000° C. to 2100° C. under an inert gas environment, and then, the polymer material is pulverized, to thereby control graphitization and crystal growth of the carbon material, thus producing a vitreous carbon material which serves as a carbon material for a power storage device.
