  A mechanism of spontaneous conformal symmetry breaking based on field
condensates in the Standard Model of strong and electroweak interactions is
suggested. It is shown that an existence of the top quark condensate can
supersede the tachyon mass term in the Higgs potential in the standard
mechanism of electroweak symmetry breaking. Considering the ratio of a field
condensate to the corresponding mass power (depending on quantum statistics)
for various fields as a conformal invariant, we obtain the Higgs boson mass to
be about $130\pm 15$ GeV.
