The PADME experiment, by using the positron beam of the INFN Frascati laboratory, looks for signals of a dark photon, $A^\prime$. By knowing the beam energy, and measuring precisely the four-momentum of the ordinary recoil photon, a signal is searched in the missing mass of the process $e^+ e^- \rightarrow A^\prime \gamma$. The precise determination of this quantity, and the capability to reject background events, are the key points for the success of the experiment. In this paper, a general description of the physics case and of the detector are given.
