The present invention provides a separator for an electrochemical device, and an electrochemical device comprising same, which comprise: a porous polymer base material; and a porous organic inorganic coating layer which is formed on at least one surface of the porous polymer base material, comprises thermally conductive inorganic particles and core-shell particles, and has the particles bound by a binder polymer, wherein the core-shell particles comprise a core part and a shell part surrounding the surface of the core part, the core part comprises an endothermic metal hydroxide, and the shell part comprises a polymer resin. Due to such configurational features, the present invention can provide the separator and the electrochemical device comprising same, which have improved heat absorption and stability. |
