  We investigate the production of the novel $P$-wave mesons $D^{*}_{0}$ and
$D^{\prime}_{1} (D_{1})$, identified as $J^{P}=0^+$ and $1^+$, in heavy $B$
meson decays, respectively. With the heavy quark limit, we give our modelling
wave functions for the scalar meson $D^{*}_{0}$. Based on the assumptions of
color transparency and factorization theorem, we estimate the branching ratios
of $B\to D^{*}_{0} \pi$ decays in terms of the obtained wave functions. Some
remarks on $D^{(\prime)}_{1}$ productions are also presented.
