Within the hidden local symmetry framework, the Dalitz decay${\eta}^{\prime}$ ${\to}$ $Ve^{+}e^{-}$ is studied with the vector mesondominance model. It is found that the partial width${\Gamma}({\eta}^{\prime}{\to}{\omega}e^{+}e^{-})$ ${\approx}$ $40$ eV andbranching ratio ${\cal B}({\eta}^{\prime}{\to}{\omega}e^{+}e^{-})$ ${\approx}$$2{\times}10^{-4}$, and ${\Gamma}({\eta}^{\prime}{\to}{\rho}e^{+}e^{-})$${\approx}$ $10{\Gamma}({\eta}^{\prime}{\to}{\omega}e^{+}e^{-})$ and ${\calB}({\eta}^{\prime}{\to}{\rho}e^{+}e^{-})$ ${\approx}$ $10{\calB}({\eta}^{\prime}{\to}{\omega}e^{+}e^{-})$. The maximum position of thedilepton distribution is $m_{e^{+}e^{-}}$ ${\approx}$ $1.33$ MeV. These decaysare measurable with the advent of high statistics ${\eta}^{\prime}$experiments.
