  We study the dynamics of the Affleck-Dine field after inflation in more
detail. After inflation, the Affleck-Dine field inevitably oscillates around
the potential minimum. This oscillation is hard to decay and can cause
accidental suppression of the consequential baryon asymmetry. This suppression
is most effective for the model with non-renormalizable superpotential
$W_{AD}\sim \Phi^4$ ($\Phi$: Affleck-Dine field). It is found that the
Affleck-Dine leptogenesis in high-scale inflation, which suffers from serious
gravitino overproduction, becomes workable owing to this effect.
