  We consider recently observed neutrinoless double beta decay in the context
of the minimal supersymmetric standard model with R-parity violating couplings
lambda^{'}. We observe that most of the current experimental bounds on the
R-parity violating couplings do not exclude the possibility that the
neutrinoless double beta decay is caused by R-parity violation. But if we
consider K-bar{K} oscillation, we observe that we have to make the R-parity
violating couplings generation-dependent to accomodate with the observed
neutrinoless double beta decay. And furthermore, we need some mechanism to
cancel the contribution to K-bar{K} mixing from a large R-parity violating
coupling. We realized this cancellation by assuming that the first- and the
second- generation of quark sector do not couple with the first-generation
lepton sector by R-parity violating couplings except the term
W=lambda_{111}^{'} L_{1} Q_{1} D_{1}^{c}, which is responsible for the observed
neutrinoless double beta decay.
