We classify models of the Dirac neutrino mass by concentrating on flavorstructures of the mass matrix. The advantage of our classification is that wedo not need to specify detail of models except for Yukawa interactions becauseflavor structures can be given only by products of Yukawa matrices. Allpossible Yukawa interactions between leptons (including the right-handedneutrino) are taken into account by introducing appropriate scalar fields. Wealso take into account the case with Yukawa interactions of leptons with thedark matter candidate. Then, we see that flavor structures can be classifiedinto seven groups. The result is useful for the efficient test of models of theneutrino mass. One of seven groups can be tested by measuring the absoluteneutrino mass. Other two can be tested by probing the violation of the leptonuniversality in $\ell \to \ell^\prime \nu \overline{\nu}$. In order to test theother four groups, we can rely on searches for new scalar particles at colliderexperiments.
