A carbon foam obtained by heat-treating a mesophase pitch whose softening
point is 300.degree. 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.degree. C. or higher and production processes of
these.
