There are provided a device for fabricating an electrode by a roll-to-roll process and a method for fabricating an electrode. The device for fabricating an electrode includes an unwinding roll and a winding roll travelling an electrode material; a film forming roll disposed between the unwinding roll and the winding roll allowing the electrode material to travel along a cylindrical surface of the film forming roll and having a cooling unit cooling the electrode material; and an evaporation unit receiving a lithium source and mounted for the received lithium source to form a thin film in the electrode material positioned on the film forming roll. Thereby, the lithium is deposited in a vacuum atmosphere such that the process is simple and the deposition rate and the deposition uniformity of lithium can be improved.
