  We have investigated the lepton flavor violation in the supersymmetric
framework assuming the large mixing angle MSW solution with the
quasi-degenerate and the inverse-hierarchical neutrino masses. In the case of
the quasi-degenerate neutrinos, the predicted branching ratio BR$(\mu \to e
\gamma)$ strongly depends on $m_\nu$ and $U_{e3}$. For $U_{e3}\simeq 0.05$ with
$m_\nu \simeq 0.3 \eV$, the prediction is close to the present experimental
upper bound if the right-handed Majorana neutrino masses are degenerate. On the
other hand, the prediction is larger than the experimental upper bound for
$U_{e3}\geq 0.05$ in the case of the inverse-hierarchical neutrino masses.
