  We discuss spontaneous baryogenesis in the warm inflation scenario. In
contrast with standard inflation models, radiation always exists in the warm
inflation scenario, and the inflaton must be directly coupled to it. Also, the
transition to the post-inflationary radiation dominated phase is smooth and the
entropy is not significantly increased at the end of the period of inflation.
In addition, after the period of warm inflation ends, the inflaton does not
oscillate coherently but slowly rolls. We show that as a consequence of these
features of warm inflation, the scenario can well accommodate the spontaneous
baryogenesis mechanism, provided that the decoupling temperature $T_{D}$ of the
baryon or the $B-L$ violating interactions is higher than the temperature of
radiation during the late stages of inflation.
