%X In this paper we consider the Beth-Salpeter(BS) equation for the bound state of two piont particles with a confining kernal. Subsequently we obtain the heavy meson wave function in the framework of heavy quark effective theory assumptions. We calculate the semileptonic weak decay of B to D and D * using the BS wave function to give q2-dependence of the form factors. The obtained results for the from factors, their slopes and curvature are consistent with the experimental data.
