Zusammenfassung:	본 발명의 일 측면은, (a) 폴리올레핀 및 기공형성제를 포함하는 조성물을 가공하여 베이스시트를 얻는 단계; (b) 상기 베이스시트를 세로방향(MD) 및 가로방향(TD)으로 연신하고, 상기 기공형성제를 제거하여 다공막을 얻는 단계; 및 (c) 상기 다공막을 가로방향(TD)으로 연신하여 열고정하는 단계;를 포함하는 분리막의 제조방법 및 이를 이용하여 제조된 분리막을 제공한다. One aspect of the present invention provides a method for manufacturing a separator, and a separator manufactured thereby, the method comprising the steps of: (a) obtaining a base sheet by processing a composition including a polyolefin and a pore forming agent; (b) obtaining a porous membrane by stretching the base sheet in the machine direction (MD) and transverse direction (TD) and removing the pore forming agent, and (c) stretching the porous membrane in the transverse direction (TD) and heat-setting same.
