  We point out that the inflaton spontaneously decays into any gauge bosons and
gauginos via the super-Weyl, Kahler and sigma-model anomalies in supergravity,
once the inflaton acquires a non-vanishing vacuum expectation value. In
particular, in the dynamical supersymmetry breaking scenarios, the inflaton
necessarily decays into the supersymmetry breaking sector, if the inflaton mass
is larger than the dynamical scale. This generically causes the overproduction
of the gravitinos, which severely constrains the inflation models.
