  The three neutrino mass matrices in the $SU(5)\times U(2)$ model are studied
focusing on the neutrino oscillation experiments. The atmospheric neutrino
anomaly could be explained by the large $\nu_{\mu} - \nu_{\tau}$ oscillation.
The long baseline experiments are expected to detect signatures of the neutrino
oscillation even if the atmospheric neutrino anomaly is not due to the neutrino
oscillation. However, the model cannot solve the solar neutrino deficit while
it could be reconciled with the LSND data.
