Abstract
Using the effective Lagrangian method, we analyze the corrections to the branching ratio b $\rightarrow$ s$\gamma$ i from the Higgs sector in the standard model. The numerical result indicates that the corrections from this sector to b $\rightarrow$ s$\gamma$ i is about -2% as mh ~ 0.5 TeV.
