  The electric dipole moments (EDMs) of the neutron and the electron are
reviewed within the framework of the supersymmetric standard model (SSM) based
on grand unified theories coupled to N=1 supergravity. Taking into account
one-loop and two-loop contributions to the EDMs, we explore SSM parameter space
consistent with experiments and discuss predicted values for the EDMs.
Implications of baryon asymmetry of our universe for the EDMs are also
discussed.
