• We study the EDM of an electron and a newtron using a Gauge Mediation SUSY Breaking (GMSB) model for the doublet-triplet splitting. We conceive the special model in which the discrete symmetry is introduced and then the gaugino mass becomes non-universal. As a result, the cancellation between chargino contributions and neutralino contributions on the EDM occurs, and those can appear the parameter regions that satisfy both soft breaking parameter of O(10^2)GeV and O(1) CP-phases.
