We propose a simple model in which MSSM plus neutrino mass term, (LH_u)^2 is supplemented by a minimal flaton sector to drive the thermal inflation, and make two crucial assumptions: the flaton vacuum expectation value generates the mu-term of the MSSM and m_L^2 +m_{H_u}^2<0. We show that our model leads to thermal inflation followed by Affleck- Dine leptogenesis along the LH_u flat direction.
