  We propose a supersymmetric composite model with three generations in which
supersymmetry and electroweak symmetry are broken dynamically, and masses of
quarks and leptons are generated without introducing any mass scales by hand.
All the mass scales in the model are expected to be generated dynamically. The
mechanism to have mass hierarchy is explicitly described, although the roughly
estimated mass spectrum of quarks and leptons does not exactly coincide with
the realistic one.
