Abstract: We study the neutralino sector of the Minimal Non-minimal SupersymmetricStandard Model MNSSM where the $\mu$ problem of the Minimal SupersymmetricStandard Model MSSM is solved without accompanying problems related with theappearance of domain walls. In the MNSSM as in the MSSM the lightest neutralinocan be the absolutely stable lightest supersymmetric particle LSP providing agood candidate for the cold dark matter component of the Universe. In contrastwith the MSSM the allowed range of the mass of the lightest neutralino in theMNSSM is limited. We establish the theoretical upper bound on the lightestneutralino mass in the framework of this model and obtain an approximatesolution for this mass.
