We study a possibility to explain neutrino masses and mixings based on supersymmetry. If we introduce a flavor diagonal but generation dependent extra U(1) gauge interaction at a TeV region, we can obtain masses and mixings of neutrinos required for the explanation of both solar and atmospheric neutrinos. In this model, differently from the usual bilinear R-parity violating scenario, the neutrino mass degeneracy can be resolved at a tree level by the neutrino-gaugino mixing caused by an R-parity violation. The model is straightforwardly extended to include the quark sector by introducing an anomalous U(1) which can be used for the Froggatt-Nielsen mechanism.
