 note = {This is a brief report on Majorana neutrino(n) mass to be studied by neutrino-less double beta decays (0nbb). The v-mass depends on the nuclear structure of the bb isotope, the effective detector volume and the background rate. Subjects discussed include 1 0nbb and v-mass, 2 0nbb nuclear matrix elements, and 3 0nbb experiments and n-mass sensitivities.},
