The hunt for the neutrino mass in the process of the neutrinoless double beta decay (0νβ β) belongs to a crucial task in the field of physics beyond the Standard model. The next generation experiment SuperNEMO, based on the NEMO-3 calo-tracko detection technique is devoted to measure this extremely rare nuclear process within the half-life sensitivity of 1 × 1026 years, which correspond to the sensitivity on the effective neutrino mass 〈mν〉 of 40 – 110 meV. In this contribution, a progress in the construction and commissioning of the first SuperNEMO module - demonstrator, is reported.
