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
