We propose a model realizes that a semi-visible dark photon which cancontribute to the anomalous magnetic moment ($g-2$) of both electron and muon.In this model, the electron $g-2$ is deviated from the Standard Model (SM)prediction by the 1-loop diagrams involving the vector-like leptons, while thatof muon is deviated due to a non-vanishing gauge kinetic mixing with photons.We also argue that the $W$-boson mass can be deviated from the SM predictiondue to the vector-like lepton loops, so that the value obtained by the CDF IIexperiment can be explained. Thus, this model simultaneously explains therecent three anomalies in $g-2$ of electron and muon as well as the $W$-bosonmass. The constraints on the $\mathcal{O}(1)~\mathrm{GeV}$ dark photon can beavoided because of the semi-invisible decay of the dark photon, $A^\prime \to 2N \to 2\nu \,2\chi \to 2\nu \,4e$, where $N$ is a SM singlet vector-likeneutrino and $\chi$ is a CP-even Higgs boson of the $U(1)^\prime$ gaugesymmetry.
