We have performed angle-resolved photoemission spectroscopy experiments on paramagnetic UFeGa5 using soft X-ray synchrotron radiation (hν=500 eV) and derived its bulk- and U 5f-sensitive electronic structure. The topology of the experimental Fermi surface is well explained by the LDA calculation treating U 5f electrons as being itinerant, suggesting that the U 5f states of this compound can be essentially understood within the itinerant-electron model.
