A unified mass matrix model of quarks and leptons with a seesaw-type form Mf=m MF-1 m is proposed on the basis of a non-standard Higgs scenario. The matrix m is provided by U(3)-family nonet bosons ϕ, and the matrix MF is a mass matrix of heavy fermions Fi corresponding to the ordinary fermions fi=νi,ei,ui,di (i=1,2,3). It is shown that a Higgs potential of ϕ with a broken U(3)-family symmetry leads to a desirable charged lepton mass formula when ME∝ \bf 1. Then, phenomenologically desirable forms of heavy quark mass matrices MQ (Q=U,D) are investigated.
