  Little Higgs models may provide a solution to the gauge hierarchy problem in
the mass of the Higgs boson. In this framework the Higgs boson is arisen as the
pseudo-Nambu-Goldstone (PNG) boson. We show that the lepton triplet introduced
in a little Higgs model explains a small mass parameter in the double see-saw
mechanism for neutrino masses, and it can also gives an explanation for the
axion like particle recently reported by PVLAS collaboration.
