The lepton family number in the Heisenberg representation are defined for the massless chiral (left-handed) neutrino which forms SU(2) doublet with the charged lepton mass eigenstate. The way of the variation of the expectation value depends on the mass hierarchies, the absolute mass of neutrinos, and their energies. For the case of Majorana neutrino, it also depends on Majorana phases. We also compare the cases for two types of the mass (Dirac and Majorana) and they show the distinctive features at low energy.
