A battery cell includes an electrode assembly, a first adhesive film, and a first adhesive layer. Outer surfaces of the electrode assembly include a first surface, a first lateral surface, a second surface opposite to the first surface, and a second lateral surface opposite to the first lateral surface. The first adhesive film adheres to the first lateral surface and extends from the first lateral surface to the first surface or extends from the first lateral surface to both the first surface and the second surface. The first adhesive layer adheres to the first surface. At least a part of the first adhesive layer overlaps the first adhesive film on a side of the first adhesive film in a thickness direction perpendicular to the first surface, and in the overlap, the first adhesive film disposed between the part of the first adhesive layer and the first surface in the thickness direction.
