Abstract
A separator for an electrochemical device and a method for manufacturing the same. Particularly, the drying rate of a composition for forming a second porous coating layer is controlled to be higher than the drying rate of a composition for forming a first porous coating layer. In this manner, it is possible to improve the interfacial adhesion between an electrode and the separator, while ensuring adhesion strength between a porous polymer substrate and a porous coating layer.
