The dark photon is a new gauge boson which arises from an extra 
gauge symmetry. In this paper, a novel dark photon production mechanism based on MeV-scale 
– collider is considered: . With the aid of PACKAGE-X, differential cross section of is obtained, as a function of the kinetic mixing parameter 
and dark photon mass 
. Taking the light-by-light scattering as background, the constraints on the dark photon parameter space for different time intervals in a MeV-scale – collider are also given.
