A supersymmetric model for accommodating the 17 KeV neutrino is proposed. The rank-two Majorana mass matrix for right-handed neutrinos can be obtained in a natural way. The neutrino spectrum is the same as that in the Glashow's model. The lifetime of the 17 KeV neutrino can satisfy the cosmological constraints.
