The present status of double beta decay experiments are reviewed. The results
of the most sensitive experiments, NEMO-3 and CUORICINO, are discussed.
Proposals for future double beta decay experiments are considered. In these
experiments sensitivity for the effective neutrino mass will be on the level of
(0.1-0.01) eV.Comment: 20 pages, 7 fugures; talk at 12-th Lomonosov Conference on Elementary
