In the case that the U(1) symmetry of inflaton is slightly broken, the baryon asymmetry of the Universe is produced by the decay of the inflaton through the Affleck-Dine mechanism. In addition to this, the modulation of the potential by the U(1) breaking term changes the abundance of the gravitational waves produced during the inflation. In this paper, we have studied the possibility that the sufficient baryon number and large amount of the tensor mode would be simultaneously produced by the inflaton.
