Abstract: A secondary battery configured to have a structure in which an electrode assembly is received in a battery case together with an electrolytic material, wherein the battery case is provided therein with a space for receiving the electrode assembly and wherein the battery case is made of a thermoplastic resin, which can be injection-molded. An injection mold may be formed such that the size of the mold corresponds to the thickness of the electrode, thereby solving a problem in which the formability of a conventional laminate sheet including a metal layer is low. In addition, a process of forming the laminate sheet and a process of sealing the battery case using a pressing member, which are essentially required in order to use the laminate sheet, may be omitted, whereby a manufacturing process is simplified and thus productivity is improved.
