A separator includes a polyolefin-based separator substrate and a coating portion formed on at least a part of an outer surface of the separator substrate. An uneven portion is formed along an outer periphery of at least one side of the separator, whereby it is possible to prevent deviation of a separator sheet from a movement direction during transfer of the separator sheet and stacking of an electrode assembly.
