We study instanton effects on B→Xsγ decay using the heavy quark effective field theory and the operator product expansion. In the dilute gas approximation the effect is negligibly small. This is in contrast to the result of the instanton effect in inclusive semileptonic b→u decay but similar to the inclusive hadronic τ decay. We discuss the similarities and differences of the B→Xsγ decay compared to inclusive hadronic τ decay and semileptonic B decay.
