  We study the electric dipole moments (EDMs) of fermions in the standard model
supplemented with right-handed neutrinos and its extension including neutrino
seesaw mechanism under the framework of minimal flavor violation (MFV). In the
quark sector, we find that the current experimental bound on the neutron EDM
does not yield a significant restriction on the scale of MFV. In addition, we
consider how MFV may affect the contribution of the strong theta-term to the
neutron EDM. For the leptons, the existing EDM data also do not lead to strict
limits if neutrinos are Dirac particles. On the other hand, if neutrinos are
Majorana in nature, we find that the constraints become substantially stronger.
Moreover, the results of the latest search for the electron EDM by the ACME
Collaboration are sensitive to the MFV scale of order a few hundred GeV or
higher. We also look at constraints from $CP$-violating electron-nucleon
interactions that have been probed in atomic and molecular EDM searches.
