Abstract

The present invention relates to a separator including a substrate layer; and a porous coating layer positioned on one side or both sides of the substrate layer, and containing a first inorganic particle, a second inorganic particle, and an acrylic-based binder, wherein a ratio of an average particle diameter (D<50>) of the second inorganic particle to an average particle diameter (D<50>) of the first inorganic particle is 1.4 to 2.0, an amount of the first inorganic particle is greater than an amount of the second inorganic particle on the basis of a total weight of the porous coating layer, and the porous coating layer has a thickness of 1.2 µm to 2.0 µm.
