The present invention is related to a pouch type lithium secondary battery. The pouch type lithium secondary battery according to the present invention may comprise an electrode assembly including a positive electrode, a separator and a negative electrode, and a pouch having a groove for receiving the electrode assembly and upper and lower portions of which are fused to each other around the groove to form flange-shaped edges. In particular, the edges may be at least partially covered at ends thereof with insulating material. As a result, a short circuit between a metal foil of the pouch and the negative electrode of the battery can be prevented, and corrosion of the battery may be also prevented.
