Experiments on x-ray photoelectron spectroscopy of Bi{sub 2}Sr{sub 2}Ca{sub 1{minus}{ital x}}Y{sub {ital x}}Cu{sub 2}O{sub {ital y}} were performed to investigate the change of valence of each atom and the distribution of Y atoms on the cation sites. The core-level binding energies of Sr and Y increased with increasing Y content and that of Bi did not change. The average valence of Cu was above 2 for 0.0{le}{ital x}{le}0.5 and below 2 for 0.8{le}{ital x}{le}1.0. Y atoms were substituted for the cations between the adjacent Cu-O planes.
