The η-meson photoproduction cross sections have been measured on the C and Cu targets for the photon energies between 600 and 1100 MeV to investigate the behavior of the S₁₁(1535) resonance in a nucleus. The excitation functions of the cross section as well as the angular and momentum distributions of η-mesons are in quantitative agreement with the Quantum Molecular Dynamics (QMD) model calculations in which the η-meson emission processes other than the S₁₁(1535) resonance are also incorporated as proposed in the η-MAID model. It is shown that the excitation of the D₁₅(1675) resonance might play an important role for Eγ>900 MeV.
