Within the Standard Model, we investigate the semi-leptonic weak decays of$J/\psi$. The various form factors of $J/\psi$ transiting to a single charmedmeson ($D^{(*)}_{(d,s)}$) are studied in the framework of the QCD sum rules.These form factors fully determine the rates of the weak semi-leptonic decaysof $J/\psi$ and provide valuable information about the non-perturbative QCDeffects. Our results indicate that the decay rate of the semi-leptonic weakdecay mode $J/\psi \to D^{(*)-}_{s}+e^{+}+\nu_{e}$ is at order of $10^{-10}$.
