  We present a composite model that is based on non-perturbative effects of N=1
supersymmetric SU(N_C) gauge theory with N_f=N_C+1 flavors. In this model, we
consider N_C=7, where all matter fields in the supersymmetric standard model,
that is, quarks, leptons and Higgs particles are bound states of preons and
anti-preons. When SU(7)_H hyper-color coupling becomes strong, Yukawa couplings
of quarks and leptons are generated dynamically. We show one generation model
at first, and next we show models of three generations.
