In this paper, we use the instantaneous Bethe–Salpeter method to calculate the semi-leptonic and non-leptonic production of the orbitally excited scalar 
in B meson decays. When the final state is 1P state 
, our theoretical decay rate is consistent with experimental data. For final state, which was observed by LHCb collaboration recently and here treated as the orbitally excited scalar , its rate is in the order of 
. We find the special node structure of wave function possibly results in the suppression of its branching ratio and the abnormal uncertainty. The 3P states production rate is in the order of 
.
