A carbon foam obtained by heat-treating a mesophase pitch whose softening point is 300° C. or less according to an elevated flow tester, whose ratio (Daromatic/Daliphatic) of the absorption intensity of an aromatic C--H stretching vibration, measured with FT-IR, to the absorption intensity of an ali
A carbon foam obtained by heat-treating a mesophase pitch whose softening point is 300° C. or less according to an elevated flow tester, whose ratio (Daromatic/Daliphatic) of the absorption intensity of an aromatic C--H stretching vibration, measured with FT-IR, to the absorption intensity of an aliphatic C--H stretching vibration, measured with FT-IR, is 4.0 or less and whose optically anisotropic content is at least 80%, a graphite foam obtained by heat-treating the carbon foam recited above at a temperature of 2,000° C. or higher and production processes of these.
