Zusammenfassung:Provided is an exterior material for an electrical storage device having a matte-finished design which is achieved by a filler-containing surface coating layer and is resistant to damage due to heat sealing, the exterior material having superior moldability. The exterior material for an electrical storage device is composed of a layered body comprising at least, in this order from the outer side, a surface coating layer, a base material layer, a barrier layer, and a thermally adhesive resin layer. The surface coating layer includes a resin and a filler. The logarithmic decrement deltaE at 200 DEG C according to a rigid body pendulum measurement of an outer surface of the surface coating layer of the layered body is not more than 0.43. 本发明提供一种抑制因热封而使含有填料的表面覆盖层所产生的消光感的外观设计受损并且成型性也优异的蓄电器件用外包装材料。该蓄电器件用外包装材料由从外侧依次至少具有表面覆盖层、基材层、阻隔层和热熔接性树脂层的叠层体构成,上述表面覆盖层含有树脂和填料,在上述叠层体的上述表面覆盖层的外侧表面的刚体摆测定中,在200℃的对数衰减率ΔE为0.43以下。
