The wave function of the vector bound state of a spinor straton-antistraton pair through scalar coupling is discussed.The Bethe-Salpeter equation of the bound state is solved numerically,and the structural wave functions of the vector bound state are given corresponding to different selection of the parametcrs of the kernel. The magnitude of various invariant functions of the wave function is determined. The validity of the Bargman-Wigner approximation is also examined.
