We have measured the branching fraction of the inclusive radiative B meson decay B → Xsγ to be Br(B → Xsγ) = (3.36 ± 0.53(stat) ± 0.42(sys)-0.54 +0.54(th)) × 10-4. The result is based on a sample of 6.07 × 106 B B̄ events collected at the γ(4S) resonance with the Belle detector at the KEKB asymmetric e+e- storage ring.
