Based on this picture we establish the Bethe-Salpeter (B-S) equation for $\\Lambda_Q$ in the leading order of $1/m_Q$ expansion. With the kernel containing both the scalar confinement and one-gluon-exchange terms we solve the B-S equation numerically. The Isgur-Wise function for $\\Lambda_b \\to \\Lambda_c$ is obtained numerically from our model. Comparison with other model calculations are also presented.
