  We are considering the cosmological consequences of an induced gravity theory
coupled to the minimal standard model of particle physics. The non-minimal
coupling parameter between gravity and the Higgs field must then be very large,
yielding some new cosmological consequences for the early Universe and new
constraints on the Higgs mass. As an outcome, new inflation is only possible
for very special initial conditions producing first a short contraction era
after which an inflationary expansion automatically follows; a chaotic
inflationary scenario is successfully achieved. The contrast of density
perturbations required to explain the seed of astronomic structures are
obtained for very large values of the Higgs mass ($M_{H} >> G_{F}^{-1/2}$),
otherwise the perturbations have a small amplitude; in any case, the spectral
index of scalar perturbations agrees with the observed one.
