摘要： Disclosed is a pouch type secondary cell. The pouch type secondary cell includes an electrode assembly including a cell and an electrode, a pouch having a receiving space configured to receive the electrode assembly therein, the pouch including upper and lower sheets configured to surround upper and lower plate surfaces of the electrode assembly respectively, and a terrace sealing formed by compressing the upper and lower sheets, which surround a terrace, in a thickness direction thereof so that the upper and lower sheets come into contact with each other, the terrace being an empty space in the receiving space excluding a space occupied by the electrode assembly. By selectively forming a sheet penetration hole in the upper and lower sheets, which close the terrace in the pouch in which the electrode assembly is received, it is possible to discharge gas generated during manufacture and to allow the sheet penetration hole to be sealed by the terrace sealing, which may provide the secondary battery capable of stably fixing the electrode assembly and preventing internal short circuits, thereby ultimately achieving excellent safety.
