  We calculated the contribution of the photon hadronic component in the
charmed structure function of the leptoproduction. The contribution comes from
scattering of the c quarks of the virtual photon on the quarks and gluons of
the proton. Comparison of our calculations with the measurements of the charm
production in $\mu^+p$-scattering by EMC shows, that contribution of resolved
photon can explain the excess of EMC data over the predictions of the
photon-gluon fusion model at large momentum transfers. Thus, one does not need
to use a non-perturbative admixture of the charmed quarks in the proton wave
function (''intrinsic charm'') to describe such an excess in EMC data.
