  Inspired by the recent HEIDELBERG-MOSCOW double beta decay experiment, we
discuss the neutrinoless double beta decay in the supersymmetric seesaw model.
Our numerical analysis indicates that we can naturally explain the data of the
observed neutrinoless double beta decay, as well as that of the solar and
atmospheric neutrino experiments with at least one Majorana-like sneutrino of
middle energy scale in the model.
