We have studied the electronic band structure and the Fermi surface of UPd3 with ultrahigh-resolution angle-resolved photoemission spectroscopy. It was found that non-dispersive U 5f "bands" are located far below the Fermi level and the main body of valence band consists of Pd 4d-U 6d hybridized dispersive bands in qualitatively good agreement with the band-structure calculation based on the localized U 5f model. We found two hole-like Fermi surfaces with a dominant Pd 4d character at Γ(A) point and an electron-like one with a U 6d nature at K(H) point.
