Three dimensional Fermi surface of TiSe₂ is investigated by means of angle-resolved photoelectron spectroscopy with synchrotron radiation. Volumetric presentation of the photoelectron intensity at the Fermi level in the k_x-k_y-k_z space well represent the DFT-calculation for the Fermi surface of TiSe_2. Change of the Fermi surface due to the CDW transition is also discussed.
