Outer packaging material for power storage device, power storage device, and method for manufacturing outer packaging material for power storage device

An outer packaging material (1) for a power storage device is provided with a base material layer (3), a metal layer (2), and a sealant layer (4). The arithmetic mean curvature (Spc (unit: mm-1)) of peak top points, the five-point peak region height (S5p ([mu] m)), the smooth rough intersection (SRC ([mu] m2)), the region parting complexity (Safc (dimensionless)), the height difference (Sk ([mu] m)) of the core, the pole height (Sxp ([mu] m)), the root mean square slope (Sdr (%)), the minimum autocorrelation length (Sal ([mu] m)), the volume (Vvc (mL/m2)) of the space of the core, and the volume (Vmc (mL/m2)) of the core in the inner surface (1a) of the outer packaging material (1) are set as a-j, respectively. The value of F defined by the following Formula 1 is greater than 0. F =-6.0 to 0.13 a to 0.51 b + 0.000073 c to 3.9 d + 0.91 e + 1.5 f to 3.9 g + 0.027 h + 2.1 i + 2.3 j... (Formula 1). 蓄电设备用外包装材料(1)包括基材层(3)、金属层(2)及密封剂层(4)。在将外包装材料(1)的内侧表面(1a)中的峰顶点的算术平均曲率Spc(单位：mm-1)、五点峰区域高度S5p(μm)、平滑粗糙交叉SRC(μm2)、区域分型复
