N2 - We calculate the two-loop diagrams that give a nonzero contribution to the electric dipole moment [Formula Presented] of a charged lepton [Formula Presented] due to possible Majorana masses of neutrinos. Using the example with one generation of the standard model leptons and two heavy right-handed neutrinos, we demonstrate that the nonvanishing result for [Formula Presented] first appears in order [Formula Presented], where [Formula Presented] is the mass of the light neutrino and the see-saw type relation is imposed. This effect is beyond the reach of presently planned experiments.
