We study the solution to the Polonyi problem where the Polonyi field weighs as O(10 TeV) and decays just before the primordial nucleosynthesis. It is shown that in spite of a large entropy production by the Polonyi field decay, one can naturally explain the present value of the baryon-to-entropy ratio, nB s ∼ 10-10-10-11 if the Affeck-Dine mechanism for baryogenesis works. It is pointed out, however, that there is another cosmological problem related to the abundance of the lightest superparticles produced by the Polonyi decay.
