Photoelectron spectroscopy has been used to study the electronic structure of the newly discovered Bi-Ca-Sr-Cu-O superconductors. A clear Fermi edge is observed showing a metallic behavior. The oxygen 1s core level shows only one peak, in contrast to previous results on YBa/sub 2/Cu/sub 3/O/sub 7-//sub delta/. We suggest that the Fermi edge observed is mainly due to electrons derived from Bi-O p bands.
