The electric dipole moment of the neutron in the supersymmetric standard models is reconsidered. Assuming {ital CP}-violating phases are not much suppressed, we explore the region of the supersymmetric mass parameters allowed by the experiments. The chargino-loop diagram gives constraints more stringently than the gluino- and neutralino-loop diagrams. It is found that the squark masses should be larger than {similar to}1 TeV, while the charginos and the neutralinos could be as light as a few hundred GeV.
