In this paper , we consider large non-Gaussianity generated after D-term inflation in the case that the adiabatic curvature perturbation produced is dominated by a right-handed ( RH ) sneutrino curvaton . The cosmic string problem can also be evaded with around 10 \% contribution to the CMB power spectrum and the spectral index n _ { s } \simeq 1 . The non-Gaussianity produced can be as large as 10 < f _ { NL } < 100 for the right-handed sneutrino mass being around m _ { \Phi } = 100 \mbox { GeV } with the Yukawa coupling \lambda _ { \nu } \sim 10 ^ { -10 } . In this case , the lightest neutrino mass is 10 ^ { -10 } \mbox { eV } which favors RH sneutrino leptogenesis .
