A device for the inductive transfer of electrical energy between a stationary coil, which can be installed in a roadway, and a secondary coil of a movable electrical load, in particular of an electrical vehicle, wherein a supply unit for supplying electrical energy is allocated to the coil. The problem of providing a maintenance-friendly, reliable, operationally secure device for inductive transfer of electrical energy, which is protected against penetration of water into the sensitive electronics, is solved in that the supply unit is arranged on a side of the coil facing away from the roadway in an installed state in a housing which is closed on top and laterally, having a housing opening open to the bottom.
