  Affleck-Dine inflation is a recently proposed model in which a single complex
scalar field, nonminimally coupled to gravity, drives inflation and
simultaneously generates the baryon asymmetry of universe via Affleck-Dine
mechanism. In this paper we investigate the supersymmetric implementation of
Affleck-Dine inflation in the use of two chiral superfields with appropriate
superpotential and K\"ahler potential. The scalar potential has a similar form
to the potential of original Affleck-Dine inflation, and it gives successful
inflation and baryogenesis. We also consider the isocurvature perturbation
evolving after crossing the horizon, and find that it is ignorable and hence
consistent with the observations.
