Abstract: An electrode sheet and a secondary battery comprising the same are provided. The electrode sheet comprises a current collector and an active material layer provided on at least one surface of the current collector. A first inorganic separation layer and a second inorganic separation layer are sequentially formed on the active material layer. The first inorganic separation layer comprises a plurality of pores having a diameter of 300 nm to 600 nm, and each of the plurality of pores extends from the first inorganic separation layer toward the second inorganic separation layer and penetrates through the second inorganic separation layer. The pore diameter of the pores in the second inorganic separation layer is uniform.
