Disclosed herein is a pouch-type battery including a cathode and an anode protruding from opposite sides of a battery case in opposite directions, wherein the pouch-type battery is constructed in a structure in which two receiving parts are formed at a one-unit sheet-type battery case in a symmetrical fashion such that an electrode assembly is received in the receiving parts, the battery case is bent between the two receiving parts (along a bending line) such that one of the receiving parts overlaps with the other receiving part while the electrode assembly is received in the other receiving part, the bent battery case being scaled, the two receiving parts are continuously formed while the two receiving parts are in contact with the bending line, and the battery case is provided at the edge thereof where the bending line runs with bent depression parts having a depth equivalent to that of the receiving parts. The pouch-type battery is manufactured with a capacity equivalent to twice that of a conventional battery through a simple assembly process, and is constructed in a structure in which the battery case is prevented from breakage during the assembly process.
