The inclusive process b→sγ is studied in the littlest Higgs model. The contributions arising from new particles are normally suppressed by a factor of O(v2/f2). Due to the large uncertainties of experimental measurements and theoretical predictions, the model parameters can escape from the constraints of present experiments provided f≥1 TeV.
