We have investigated the effects of Fe on the structure and properties of 110 K phase superconductor Bi-Pb-Sr-Ca-Cu-O. The zero resistance temperature decreases and the x-ray diffraction intensity ratio of (200) to (0014) peak increases, with the increasing of the Fe atom concentration. These samples are of single (2223) phase structure. It may be suggested that a 95 K superconducting phase exists. Its structure is very similar to that of the Bi{sub 2}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub {ital y}} phase. The Fe atoms make the 110 K phase turn into the 95 K phase.
