A separator according to the present invention comprises: a polyolefin-based separator substrate; and a coated portion formed on at least a portion of an outer surface of the separator substrate, wherein the separator may be configured such that a concave-convex portion is formed along the outer periphery of at least one side of the separator, and the separator can be prevented from deviating from a traveling direction during movement of a separator sheet or stacking of an electrode assembly. La présente invention concerne un séparateur comprenant : un substrat de séparateur à base de polyoléfine ; et une partie revêtue formée sur au moins une partie d'une surface externe du substrat de séparateur, le séparateur pouvant être configuré de telle sorte qu'une partie concave-convexe est formée le long de la périphérie externe d'au moins un côté du séparateur, et le séparateur pouvant être empêché de dévier d'une direction de déplacement pendant le mouvement d'une feuille de séparateur ou l'empilement d'un ensemble électrode. 본원발명에 따른 분리막은, 폴리올레핀 계열의 분리막 기재, 및 상기 분리막 기재의 외면 중 적어도 일부에 형성된 코팅부를 포함하고, 적어도 일측 외주변을 따라 요철부가 형성된 형태일 수 있는 바, 분리막 시트의 이동 과정 및 전극조립체 적층시 주행 방향에서 벗어나는 것을 방지할 수 있다.
