We consider the generation of the baryon asymmetry of the universe through R-parity violation in a scenario in which the out-of-equilibrium condition is satisfied by making the electroweak phase transition first order. We study all the R-parity-violating interactions which can generate (B-L) asymmetry which then converts to the baryon asymmetry of the universe. We demonstrate that CP-violating sfermion decays contribute more than that of the neutralino decays in the generation of (B-L) asymmetry.
