We have studied the energy spectra of polaron in SSH model by using a selfconsistent ap-proach. Four new localized electronic state are discovered. They form four discrete levels outside the conduction and valence bands: one locates near the battom of the conduction band and one near the top of conduction bunt, another two are symmetrically near the valence band. Those at the bottom of conduction band and top of valence band only exist in the limited range of coupling constant λ.
