Abstract: A method for manufacturing a battery pack is provided in which a cell 2 that includes a contact pad 9 attached thereto is placed on a die 24, and a cover that is integrated with the cell 2 and the contact pad 9 is molded. The contact pad 9 includes a body that includes an opening formed therein, and an external connection terminal disposed at the position of the opening. The cover is molded by bringing the surface of the body into contact with a die 26 and injecting a resin into a space surrounded by dies 24, 25, and 26 and the cell 2. The contact is a flat surface contact without fitting. Accordingly, resin leakage can be prevented with a simple structure in an integrally-molded type battery pack, and thus stable molding can be performed.
