The present invention addresses the problem of providing a battery pack which is capable of suppressing the thickness of an entire battery, while securing the fixing of film-sheathed batteries to one another. This battery pack has: a film-sheathed battery assembly (2) wherein a plurality of film-sheathed batteries (10) are laminated; and at least one fixing member (3) which faces a side surface of the film-sheathed battery assembly (2). The film-sheathed batteries (10) each have a power generating element (11), and a film sheath material (12) which forms an internal space (13) that is capable of housing the power generating element (11) together with an electrolyte. The film sheath material (12) has: a housing section (14) which forms the internal space (13); and a sealing section (15) which extends from the housing section (14) to the fixing member (3), and seals the internal space (13). The sealing section (15) is fixed by the fixing member (3) in a state in which the sealing section (15) is inserted in a slit (4) formed in the fixing member (3). |
