  In the framework of the vector dominance model (VDM) new contribution into
the cross-section of $D^*$-meson photoproduction at HERA has been estimated.
This contribution is due to the interaction of the virtual vector $c\bar
c$-mesons from photon with the proton. It has been shown that the mechanism
under discussion plays the essential role for all values of transverse momentum
of $D^*$-mesons at HERA. Taking into account for the contribution of this
mechanism improves the description of the experimental cross section
distribution.
