Penetration of vortices into a thin superconducting film and the edge barrier arising in a transverse magnetic field are considered. The vortex Gibbs energy is calculated on the base of the Kogan’s solution for the Pearl’s vortex situated near the film edge. The penetration field and the magnetization in the critical state are calculated. The influence of the edge barrier on magnetization of high-Tc thin films is estimated.
