Angle-resolved photoemission measurement with synchrotron radiation has been performed on single-crystal Bi2Sr2CaCu2O8. Two dispersive bands intersecting the Fermi level midway between the 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-Tc superconductor as well as band renormalization due to the strong electron correlation.
