Abstract

Provided is a battery pack capable of advantageously maintaining conduction. In the embodiment of the battery pack disclosed herein includes a stacked body in which a plurality of unit cells are stacked in a predetermined stacking direction, and a housing that accommodates the stacked body. An insulating member having an insulating property is arranged inside the housing. Here, a positive-negative electrode joint in which at least a part of the positive electrode terminal of one unit cell and at least a part of the negative electrode terminal of the other unit cell are joined to each other is present between the unit cells adjacent in the stacking direction, and the positive-negative electrode joints are embedded with the insulating member in order to prevent a liquid from penetrating from the outside.
