Abstract: The present disclosure relates to a power storage device packaging material. The power storage device packaging material has a structure including at least a substrate layer, an adhesive layer, a metal foil layer, a sealant adhesive layer, and a sealant layer laminated in this order. The substrate layer is formed of a polyester film exhibiting ΔA, as expressed by the following Formula (1), of 10% or more and a 50% elongation stress of 75 MPa or more after heat treatment at 160°C. Δ ⁢ A = break elongation after 160 ° C heat treatment − break elongation before 160 ° C heat treatment
