Abstract：With the same constituents of quark and antiquark, the p-wave state has a higher mass than the corresponding s-wave state, but the relativistic corrections are much larger in the processes of which p-wave mesons are involved. Considering this, the relativistic Bethe–Salpeter method is applied to estimate the branching fractions of semileptonic decays B(s)→D*(sJ)lν (J=0,2). Our predictions are Br[B0s→D*+s0(2317)l?ν]=0.50%, Br[B0s→D*+s2(2573)l?ν]=0.40%, Br[B?→D*00(2400)l?ν]=0.79%, Br[B?→D*02(2460)l?ν]=0.28%, Br[B0→D*+0(2400)l?ν]=0.58% and Br[B0→D*+2(2460)l?ν]=0.27%.
