<p>The present invention relates to a battery case of excellent productivity and a secondary battery comprising the same. More particularly, the present invention relates to a battery case of a laminate sheet structure where a receiving part corresponding to the shape of en electrode assembly is formed. The battery case includes an inner polymer layer touching the receiving part, a barrier layer preventing the movement of material, and an outer coating layer of a polymer film. At least one flow path where a fluid moves along the surface is formed on the surface of the inner polymer touching the receiving part.</p> |
