  In composite Higgs models it was pointed out that there is a possibility to
violate CP symmetry dynamically. We demonstrated a simple model of dynamical CP
violation in composite Higgs models. We calculated the neutron electric dipole
moment in our model and the constraint for our model is discussed. (Talk
presented at the Third KEK Topical Conference on CP Violation, 16-18 November,
1993. The main part of this talk is based on the work in collaboration with S.
Hashimoto and T. Muta.)
