The possibility of the realization of a chaotic inflationary scenario is investigated in curved spacetime in which the inflaton couples nonminimally with the spacetime curvature such as (1/2{ξ}Rφ². It is found that the coupling effect prevents the scenario from working unless {ξ} is at least smaller than 10^-3 or negative.
