We have discussed predictions of $|U_{e3}|$ and $J_{CP}$ in the framework ofthe neutrino mass matrix with two zeros. In the case of the best fit values of$\tan^2\theta_{12}$, $\tan^2\theta_{23}$, $\Delta m^2_{\rm sun}$ and $\Deltam_{\rm atm}^2$, the prediction of $|U_{e3}|$ is $0.11\sim 0.14$. The lowerbound of $|U_{e3}|$ is 0.05, which depends on $\tan\theta_{12}$ and$\tan\theta_{23}$. We have investigated the stability of these predictionstaking account of small corrections to zeros, which may come from radiativecorrections or off-diagonal elements of the charged lepton massmatrix. The lower bound of $|U_{e3}|$ comes down considerably due to the smallcorrections to zeros.Comment: Figures and discussions are adde
