Zusammenfassung:	The present invention relates to a method for manufacturing a micro-porous membrane. More specifically, the present invention relates to a method for manufacturing a micro-porous membrane having excellent heat resistance and transparency. More specifically, the present invention relates to a method for manufacturing a micro-porous membrane comprising a step in which a resin solution containing a polymer resin, a good solvent, a bad solvent, and a pore control material which does not dissolve in the good solvent but dissolves in the bad solvent is applied on a substrate to manufacture a membrane, and the membrane is soaked in a leachate solvent having compatibility with the good solvent and the bad solvent to remove the good solvent and the bad solvent. 본 발명은 미세다공막의 제조방법에 관한 것으로, 더욱 구체적으로 내열성 및 투과도가 우수한 미세다공막을 제조하는 방법에 관한 것이다. 더욱 구체적으로 고분자 수지, 양용매, 빈용매 및 상기 양용매에는 녹지 않고 빈용매에는 녹는 기공조절물질을 포함하는 수지용액을 기재 위에 도포하여 제막하고, 상기 양용매 및 빈용매와 상용성을 가지는 침출 용매에 담가 상기 양용매 및 빈용매를 제거하는 단계를 포함하는 미세다공막의 제조방법에 관한 것이다.
