The generic analytic expressions are derived for cosmological observables with the product-separable as well as additive-separable potentials when the non-minimal coupling term is dominated by one of the two fields. A hybrid model of the inflaton potential $V=\\mu^2 \\phi^2 \\left[1+\\cos(\\chi/\\sigma)\\right]$ with a non-minimal coupling $K=\\alpha \\phi$, which guarantees the flatness, is closely examined as a concrete example.
