description	To provide: a sealant film for a power storage device exterior material which has excellent slipperiness, does not have a defect of a winding form due to a wrinkle and a grain-like defect caused by entanglement of air in a film forming and laminating process, does not have a die lip stain or a process roll stain in film forming, and has excellent process passableness, has high heat sealing strength and laminate strength, produces no defect with a ring shape due to winding tightness even when aging is conducted after lamination, can maintain an amount of a lubricant on a film surface within an appropriate range, does not cause mold contamination in drawing, and is excellent in easy lubricity, heat sealability, lamination property, and drawing moldability; and a power storage device exterior material using the same.SOLUTION: A sealant film for a power storage device exterior material is a three layer laminated film of (surface layer A)/(base material layer B)/(surface layer C). The surface layer A contains an ethylene-propylene random copolymer as a main component and contains particles having an average particle diameter of more than 4 μm in an amount of more than 6,000 ppm. The base material layer B contains a propylene-based copolymer as a main component and contains particles having an average particle diameter of more than 4 μm, and the content thereof is less than the content of the particles having an average particle diameter of more than 4 μm in the surface layer A. The surface layer C contains an ethylene-propylene random copolymer as a main component.SELECTED DRAWING: None 【課題】滑り性に優れて製膜およびラミネート工程での皺やエアー巻き込みによるツブ欠点による巻き姿の欠点がなく、また製膜時の口金リップ汚れや工程ロールの汚れもなくて工程通過性に優れ、ヒートシール強度およびラミネート強度が高く、ラミネート後にエージングしても巻き締まりによるリング状の欠点がなく、フィルム表面の滑剤量を適切な範囲内に維持できて絞り成型の金型汚れがなく、易滑性、ヒートシール性、ラミネート性、絞り成型性に優れた蓄電デバイス外装材用シーラントフィルムおよびそれを用いた蓄電デバイス外装材を提供する。【解決手段】表層Ａ／基材層Ｂ／表層Ｃの３層積層フィルムであって、表層Ａがエチレン・プロピレンランダム共重合体を主成分として、平均粒子径が４μｍ超の粒子を６０００pｐｍ超含有し、基材層Ｂがプロピレン系共重合体を主成分として、平均粒子径が４μｍ超の粒子を含有し、その含有量が上記表層Ａの平均粒子径が４μｍ超の粒子含有量未満であり、表層Ｃはエチレン・プロピレンランダム共重合体を主成分とする蓄電デバイス外装材用シーラントフィルム。【選択図】なし
