Recently a model of chaotic inflation was proposed in which the right-handed sneutrinos drive the baryogenesis. We study some of the details of the model, particularly the aspect of $\mathrm{CP}$ violation, and determine the number of right-handed sneutrinos required for the viability of such models.
