  We have already proposed a quark and lepton mass matrix model based on
U(3)$\times$U(3)$'$ family symmetry as the so-called Yukawaon model, in which
the U(3) symmetry is broken by VEVs of flavons $(\Phi_f)_i^{\ \alpha}$ which
are $({\bf 3}, {\bf 3}^*)$ of U(3)$\times$U(3)$'$. The model has successfully
provided the unified description of quark and lepton masses and mixings by
using the observed charged lepton masses as only family-number dependent input
parameters. Our next concern is scales of VEVs of the flavons. In the present
paper, we estimate the magnitudes of the VEV scales of flavons of the model
which is newly reconstructed without changing the previous phenomenological
success of parameter fitting for masses and mixings of quarks and leptons. We
estimate that VEVs of flavons with $({\bf 8+1}, {\bf 1})$, $({\bf 3}, {\bf
3}^*)$, and $({\bf 1}, {\bf 8+1})$ are of 25the orders of $10$ TeV, $10^4$ TeV,
and $10^7$ TeV, respectively.
