Abstract: Disclosed herein is a pouch-shaped battery cell configured to have a structure in which an electrode assembly is received in a pouch-shaped battery case together with an electrolytic solution, wherein the pouch-shaped battery case is made of a laminate sheet including a metal layer and a resin layer, an upper edge of the pouch-shaped battery case, from which electrode terminals protrude outward, and opposite side edges of the pouch-shaped battery case, which are adjacent to the upper edge of the pouch-shaped battery case, are thermally fused to constitute a sealed portion of the pouch-shaped battery case, the opposite side edges of the pouch-shaped battery case being bent perpendicularly from the upper edge of the pouch-shaped battery case toward an electrode assembly receiving unit for receiving the electrode assembly, and a protective film is attached so as to wrap the perpendicularly bent opposite side edges of the pouch-shaped battery case.
