We have studied the electronic band structure and the Fermi surface of paramagnetic URu2Si2 with high-resolution angle-resolved photoemission spectroscopy. It was found that Ru 4d bands form a main body of the valence band and exhibit a remarkable energy dispersion in qualitatively good agreement with the band structure calculation. In addition to the dispersive Ru 4d bands, we found a less dispersive band near the Fermi level, which is assigned to the U 5f-Ru 4d hybridized band forming a hole-like Fermi surface at Z point in the Brillouin zone.
