A set of resistivity-temperature ({ital R}-{ital T}) curves measured under various applied fields in a high-{ital T}{sub {ital c}} Bi-Pb-Sr-Ca-Cu-O thin film which has a zero-resistance temperature {ital T}{sub {ital c}0} of 110 K is reported. The remarkable broadening of the transition width is discussed under the flux-creep model, considering the very short coherence length of this oxide superconductor. The resistivity is thermally activated, which is consistent with the Arrhenius law with a magnetic field and orientation-dependent activation energy {ital U}{sub 0}({ital H},{Theta}). The {ital U}{sub 0}({ital H},{Theta}) has a very high value of 381.6 meV under a field of 0.1 T parallel to the {ital c} axis. The upper critical field {ital H}{sub {ital c}2} determined from these {ital R}-{ital T} curves shows high values and the effect of flux creep to the {ital H}{sub {ital c}2}(0) is examined by the irreversible behavior with the giant'' flux-creep model.
