  We call attention to the fact that the gauge symmetry $SU(3)\times
SU(2)_{_L}\times U(1)$ of the Standard Model can be easily and naturally
extended by the local conformal symmetry connected with the possibility of
choosing the local length scale. Restricting the admissible interactions to the
lowest order conformal invariant interactions one gets the unique form of total
lagrangian. It contains all Standard Model fields and gravitational
interaction. Using the unitary and the conformal gauge conditions we can
eliminate all four real components of the Higgs doublet in this model. However
the masses of vector mesons, leptons and quarks are automatically generated and
are given by the same formulas as in the conventional Standard Model. In this
manner one gets the mass generation without the mechanism of spontaneous
symmetry breaking and without the remaining real dynamical Higgs field.
