We interpret the scalar B{sub s0}*(5725) as an S-wave BK molecular bound state in the Bethe-Salpeter approach. In the ladder and instantaneous approximation, with the kernel induced by {rho} and {omega} exchanges, we establish the Bethe-Salpeter equation for B{sub s0}*(5725). We find that the bound state of BK can exist. We also calculate the isospin-violating decay width of the process B{sub s0}*(5725){yields}B{sub s}{pi}{sup 0} through exchanging K{sup *} and B{sup *} mesons including the {eta}-{pi}{sup 0} mixing effect. We hope that the obtained decay width is instructive for the forthcoming experiment.
