  We propose a curvaton model in which the initial condition of the curvaton
oscillation is determined by its attractor behavior during inflation. Assuming
a chaotic inflation model, we find that the initial condition determined by the
attractor behavior is appropriate to generate a sizable non-Gaussianity
contribution to the curvature perturbation, which will be tested in the
foreseeable future. Implications on the thermal history of the universe and on
particle physics models are also discussed.
