Angle-resolved photoemission measurements have been made on the recently discovered high-T/sub c/ superconductor Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub x/. From the results, E vs k/sub X/ dispersion curves have been obtained along two principal symmetry directions in the two-dimensional Brillouin zone. Compared to results of one-electron band calculations, the observed bands are shifted and distorted by strong correlation effects. One band intersects the Fermi level. This band is assigned to the renormalized ''heavy-electron'' band.
