This exterior material for an electrical storage device is composed of a stack comprising at least, in this order from an outer side, a surface coating layer, a base material layer, a barrier layer, and a thermal adhesive resin layer. The surface coating layer includes a resin and particles, wherein, with respect to a cross section in a thickness direction of the surface coating layer, the hardness of the resin in the surface coating layer as measured by nanoindentation technique in a 23°C environment is not more than 420.4 MPa. |
