It is shown that at HERA energies the contribution of the charm quark excitation in the photon in the inclusive charm production at $\pt>5$ GeV/c dominates over the other resolved photon contribution via the gluon content of the photon and it is about 30\% of the contribution of the $c\bar c$-pair production via the photon-gluon fusion mechanism.LaTeX, 4 pages, 4 figures are not includedHigh Energy Physics - Phenomenologytext
