  We point out that supergravity effects enable the inflaton to decay into all
matter fields, including the visible and the supersymmetry breaking sectors,
once the inflaton acquires a non-vanishing vacuum expectation value. The new
decay processes have great impacts on cosmology; the reheating temperature is
bounded below; the gravitinos are produced by the inflaton decay in a broad
class of the dynamical supersymmetry breaking models. We derive the bounds on
the inflaton mass and the vacuum expectation value, which severely constrain
high-scale inflations such as the hybrid and chaotic inflation models.
