Abstract: We investigate inflation models in Jordan frame supergravity, in which an inflatonnon-minimally couples to the scalar curvature. By imposing the condition that an inflatonwould have the canonical kinetic term in the Jordan frame, we construct inflation modelswith asymptotically flat potential through pole inflation technique and discuss their relationto the models based on Einstein frame supergravity. We also show that the model proposedby Ferrara et al. has special position and the relation between the K ̈ahler potential and theframe function is uniquely determined by requiring that scalars take the canonical kineticterms in the Jordan frame and that a frame function consists only of a holomorphic term(and its anti-holomorphic counterpart) for symmetry breaking terms. Our case correspondsto relaxing the latter condition.
