The [ital n] fermion generation extension of the Nambu--Jona-Lasinio mechanism of spontaneous breaking of the electroweak gauge group SU[sub [ital L]](2)[times]U[sub [ital Y]](1) is proven in the bubble approximation. When both the minimal Higgs condition and the gap equation are satisfied, the explicit calculations of the propagators for bound states indicate that only a neutral massive Higgs boson and a neutral and two charged massless Goldstone bosons emerge from the theory and they are now some definte combinations of the spin-zero bound state modes consisting of the [ital n] generations of fermions. The mass of the Higgs boson is restricted between the double mass of the lightest and the heaviest fermions but more approaches the latter. We also give the inverse propagators for the charged and the neutral electroweak gauge bosons including the insertion of the three Goldstone bosons in the vacuum polarizations and display the composite Higgs mechanism generating the masses of the [ital W][sup [minus plus]] and [ital Z][sup 0] bosons.
