  We study the capability of generating correct flavor neutrino mass matrix in
a scalar clockwork model. First, we assume that the flavor structure is
controlled by the Yukawa couplings as same as the standard model. In this case,
the correct flavor neutrino mass matrix could be obtained by appropriate Yukawa
couplings $Y_{\ell^\prime\ell}$ where $\ell^\prime, \ell = e, \mu, \tau$. Next,
we assume that the Yukawa couplings are extremely democratic
$|Y_{\ell^\prime\ell} |=1$. In this case, the model parameters of the scalar
clockwork sector, such as the site number of a clockwork gear in a clockwork
chain, should have the flavor indices $\ell^\prime$ and/or $\ell$ to generate
correct flavor neutrino mass matrix. We show some examples of the assignments
of the flavor indices which can yield the correct flavor neutrino mass matrix.
