The dispersion relations for the forward scattering amplitudes are applied to estimate the nuclear many-body effect to the amplitudes which describe the kaon-nucleon scattering in nuclei and to obtain an optical model potential. The analysis is made of the assumption that only the effect of the Pauli principle to the intermediate states of the process plays a significant role and that of the multiple scatterings can be neglected. It is shown that, if the Y resonant states consist of the K^^--N bound systems, in nuclei the K^--p forward scattering amplitude can be positive at low energies, i. e. effectively attractive potential, even if the Dalitz-Tuan (-) solutions are adopted for the free K^--p scattering.
