• We discuss the spontaneous baryogenesis mechanism in flat directions. After identifying the Nambu-Goldstone mode which derivatively couples to the associated U(1) current, we show that spontaneous baryogenesis can be naturally realized in the context of the flat direction. As an application, we discuss baryogenesis in a flat direction with vanishing B-L charge, especially, with neither baryon nor lepton charge, which was recently proposed by Chiba and us.
