The separator includes a porous substrate and a coating layer on at least one surface of the porous substrate. The coating layer includes a cross-linked product of a binder and a cross-linking agent, a filler, and an adhesive binder. The binder includes a (meth)acryl-based binder including a structural unit derived from (meth)acrylate or (meth)acrylic acid, a cyano group-containing structural unit, and a sulfonate group-containing structural unit. The cross-linking agent includes a carbodiimide-based cross-linking agent. The filler includes a filler having a particle diameter D100 of 1.0 m or less. The adhesive binder includes a cross-linked (meth)acryl-based adhesive binder.",
