We propose a simple model in which the MSSM plus neutrino mass term (LH_μ)^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 μ-term of the MSSM and m^2_L+m^2_H_μ<0. We show that our model leads to thermal inflation followed by Affleck-Dine leptogenensis along the LH_μ flat direction.
