Angle-resolved photoemission measurement with synchrotron radiation has been performed on single-crystal Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub 8/. Two dispersive bands intersecting the Fermi level midway between the GAMMA point and the Brillouin-zone boundary were observed. The other bands with higher binding energy are almost dispersionless in contrast with the band-structure calculation. The present experimental result indicates the existence of a Fermi surface and Fermi-liquid states in the high-T/sub c/ superconductor as well as band renormalization due to the strong electron correlation.
