Abstract : The NEMO 3 experiment is devoted to the search for the neutrinoless double beta decay, a leptonic number violating second order weak process which is still to be discovered. The detector has been taking data in the LSM laboratory since 2003. Latest NEMO 3 results for several double beta decay emitters are presented here. The next generation SuperNEMO project, which aims to improve sensitivity to double beta decay by two orders of magnitude using NEMO 3 technique is also briefly described.
