New experimental data on the photoproduction of η-mesons on protons are used to construct an isobaric model of this process from the reaction threshold to a photon energy of 1150 MeV. The entire data array is satisfactorily described with allowance for S11 (1535), S11(1650), P 11(1440), P,13(1720), DI3(1520), and F15(1680) resonances. The properties of these resonances required for this description are given.
