In order to search the pentaquark state \Theta ⁺, the \gamma n \to K⁺K^-n reaction has been measured at the Laser Electron Photon facility at SPring-8 (LEPS), where the photon beam is produced by the backward Compton scattering of laser photons off the 8-GeV electrons circulating in the storage ring. The present status and prospects of the experimental study of the  \Theta ⁺ at the LEPS are reported.
