  We consider a possibility that electroweak symmetry breaking (EWSB) is
triggered by a fundamental Higgs and a composite Higgs arising in a dynamical
symmetry breaking mechanism induced by a new strong dynamics. The resulting
Higgs sector is a partially composite two-Higgs doublet model with specific
boundary conditions on the coupling and mass parameters originating at a
compositeness scale. The phenomenology of this model is discussed including the
collider phenomenology at LHC and ILC.
