The graphite conductivity is evaluated for frequencies between 0.1 eV, the energy of the order of the electron-hole overlap, and 1.5 eV, the electron nearest hopping energy. The in-plane conductivity per single atomic sheet is close to the universal graphene conductivity e2/4ℏ and, however, contains a singularity conditioned by peculiarities of the electron dispersion. The conductivity is less in the c−direction by the factor of the order of 0.01 governed by electron hopping in this direction.
