We studied radiative B meson decays with the Belle detector. We measured the following branching fractions; Br(B->K*0(892)\gamma) = (49.6 \pm 6.7 \pm 4.5) x 10^{-6}, Br(B->K*+(892)\gamma) = (38.9 \pm 9.3 \pm 4.1) x 10^{-6}, Br(B->Xs\gamma) = (3.39 \pm 0.53 \pm 0.42 +0.51-0.55) x 10^{-4}. We also set an upper limit for B -> \rho\gamma as Br(B->\rho\gamma)/Br(B->K*(892)\gamma) < 0.19 at 90% confidence level.
