1. A winding device for manufacturing an electrode assembly, the winding device comprising:
a main body portion;
a winding core configured to wind an electrode and a separation film to form the electrode assembly; and
a foreign particle remover connected to the main body portion, the foreign particle remover being configured to remove foreign particles from in between the winding core and the foreign particle remover,
wherein the foreign particle remover surrounds the winding core while being spaced from the winding core, and
wherein the foreign particle remover includes an inflow portion extending through an outer surface of the foreign particle remover through which the electrode and the separator enter while being wound by the winding core such that the foreign particle remover removes the foreign particles from in between the winding core and the foreign particle remover as the electrode and the separator enter the foreign particle remover through the inflow portion.
