A carbon foam obtained by heat-treating a mesophase pitch whose softening point is 300&deg; C. or less according to an elevated flow tester, whose ratio (Daromatic/Daliphatic) of the absorption intensity of an aromatic C&mdash;H stretching vibration, measured with FT-IR, to the absorption intensity of an aliphatic C&mdash;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&deg; C. or higher and production processes of these.
