  We study baryogenesis in a hybrid inflation model which is embedded to the
minimal supersymmetric model with right-handed neutrinos. Inflation is induced
by a linear combination of the right-handed sneutrinos and its decay reheats
the universe. The decay products are stored in conserved numbers, which are
transported under the interactions in equilibrium as the temperature drops
down. We find that at least a few percent of the initial lepton asymmetry is
left under the strong wash-out due to the lighter right-handed (s)neutrinos. To
account for the observed baryon number and the active neutrino masses after a
successful inflation, the inflaton mass and the Majorana mass scale should be
$10^{13}\,{\rm GeV}$ and ${\cal O}(10^{9}$-$10^{10})\,{\rm GeV}$, respectively.
