  The Higgs sector which is extended from the standard model could generally
become an origin of CP violation. In the model with two doublet and one triplet
Higgs fields on SU(2) symmetry, we study the electric dipole moment (EDM) of
the electron whose non-vanishing value has not yet been established
experimentally. The Higgs potential is assumed to be consistent with
supersymmetric theory, though supersymmetric particles are not taken into
consideration explicitly. While the parameter values of the model are severely
constrained by the properties of the observed Higgs boson, certain ranges lead
to a magnitude for the electron EDM around the experimental upper bound.
Signatures of the extra Higgs bosons in collision experiments are discussed
briefly.
