The seesaw mechanism is the most attractive mechanism to explain the smallneutrino masses, which predicts the neutrinoless double beta decay($0\nu\beta\beta$) of the nucleus. Thus the discovery of $0\nu\beta\beta$ isextremely important for future particle physics. However, the present data onthe neutrino oscillation is not sufficient to predict the value of $m_{ee}$ aswell as the neutrino mass $m_\nu^i$. In this short article, by adopting asimple and consistent Froggatt-Nielsen model, which can well explain theobserved masses and mixing angles of quark and lepton sectors, we calculate thedistribution of $m_{ee}$ and $m_\nu^i$. Interestingly, a relatively large partof the preferred parameter space can be detected in the near future.
