Abstract
A battery packaging material that is unlikely to develop pinholes or cracks during molding, and has excellent moldability, comprising at least an aluminum alloy foil layer, wherein for any 100 aluminum alloy grains positioned within a field of view of a scanning electron microscope in a cross section of the aluminum alloy foil layer in a thickness direction, an average grain diameter, which is an average value of a maximum diameter x of the 100 grains, is 10.0 μm or less, where the maximum diameter x is defined as a linear distance connecting a leftmost end of each of the grains in a direction perpendicular to the thickness direction and a rightmost end of the grain in the direction perpendicular to the thickness direction.
