Abstract

The present invention relates to a manufacturing method of a battery pack including plate-shaped battery cells arranged on a plane so that electrode terminals thereof face each other, including: (a) a process of electrically connecting electrode terminals of battery cells to an electrode terminal connecting portion of a protection circuit board (PCB); (b) a process of mounting the battery cells connected to the PCB in a mold provided with two or more injection holes for a thermoplastic resin; (c) a process of injecting a thermoplastic resin through the injection holes to form a molding frame made of thermoplastic resin on an outer periphery of the PCB and the battery cells; and (d) a process of solidifying the molding frame.
