Abstract
One aspect of the present invention provides a method of manufacturing a separator including: (a) obtaining a laminate by laminating a first porous support and a second porous support; (b) forming a functional layer by applying a composition including a binder and a solvent on both sides of the laminate and drying the composition; and (c) dividing the laminate into two separators along an interface formed by the lamination, and a separator manufactured using the method.

A method of manufacturing a separator, including:
- (a) laminating a first porous support and a second porous support to obtain a laminate;
- (b) forming a functional layer by applying a composition including a binder and a solvent on both sides of the laminate and drying the composition;
- and
- (c) dividing the laminate into two separators along an interface formed by the lamination,
- wherein the thickness of each of the first porous support and the second porous support is 10 μm or less, and
- wherein the first porous support and the second porous support are pressed to face each other during the lamination, and both ends of the first porous support and the second porous support in the transverse direction (TD) are attached to each other by a physical means selectively applied to both ends in the transverse direction (TD) of the first porous support and the second porous support.
