At the quark level there are basically two types of contributions of R-parity violating supersymmetry (R p SUSY) to neutrinoless double beta decay: the short-range contribution involving only heavy virtual superpartners and the long-range one with the virtual squark and neutrino. Hadronization of the effective operators, corresponding to these two types of contributions, may in general involve virtual pions in addition to close on-mass-shell nucleons. From the previous studies it is known that the short-range contribution is dominated by the pion exchange. In the present paper we show that this is also true for the long-range R p SUSY contribution. Therefore, we conclude that the R p SUSY contributes to the neutrinoless double beta decay dominantly via charged pion exchange between the decaying nucleons.
