We find the natural embedding of the (R+R2) inflationary model into the recently constructed F(R) supergravity. It gives a simple and viable realization of chaotic inflation in supergravity. The only requirement for a slow-roll inflation is the existence of the R3 term with an anomalously large coefficient in Taylor expansion of the F(R) function.
