We present a novel realization of Starobinsky-type inflation within Supergravity using two chiral superfields. The proposed superpotential is inspired by induced-gravity models. The Kähler potential contains two logarithmic terms, one for the inflaton T and one for the matter-like field S, parameterizing the SU(1,1)/U(1)×SU(2)/U(1) Kähler manifold. The two factors have constant curvatures −m/n and 2/n{sub 2}, where n, m are the exponents of T in the superpotential and Kähler potential respectively, and 0
