Zusammenfassung:	Disclosed is a method for manufacturing a separator for a lithium secondary battery interposed between a positive electrode and a negative electrode, wherein the method includes the steps of: preparing a separator substrate; forming a ceramic coating layer by applying a first coating solution containing a ceramic material to the surface of the separator; and forming a reaction layer which scatters X-rays by applying a second coating solution containing a metal compound to an edge of the upper surface of the ceramic coating layer where the negative electrode and positive electrode are not in contact with each other. 양극과 음극 사이에 개재되는 리튬이차전지용 분리막을 제조하는 방법으로서, 분리막 기재를 준비하는 단계; 세라믹 물질이 포함된 제1코팅액을 분리막의 표면에 도포하여 세라믹 코팅층을 형성하는 단계; 양극과 음극이 접하지 않는 세라믹 코팅층의 상면 가장자리에 금속화합물을 포함하는 제2코팅액을 도포하여 X선을 산란시키는 반응층을 형성하는 단계;를 포함하는 리튬이차전지용 분리막 제조방법이 소개된다.
