description One aspect of the present invention provides a separator including a porous substrate, and a heat-resistant layer disposed on at least one surface of the porous substrate and including inorganic particles, wherein the ratio (F2/F1) of air permeability (F2, sec/100 mL) in a curved surface with a radius of curvature of 10 mm of the separator to the air permeability (F1, sec/100 mL) in a flat surface of the separator is 1.5 or less, and an electrochemical device including the same.
