A phenomenological neutrino mass matrix is proposed to explain the solar andatmospheric neutrino deficits and to present the neutrino as a candidate of hotdark matter in the $3\nu_L+3\nu_R$ framework. The realization of mixing angleswhich can explain the solar and atmospheric neutrino problems is taken as thefirst criterion in this construction. The differences among neutrino masseigenvalues are introduced as a perturbation. In this scheme the structure of acharged lepton mass matrix is not severely constrained by the solar andatmospheric neutrino data.Comment: 8 pages, latex, minor changes and a new reference added, to be published in Prog. Theor. Phy
