Zusammenfassung:	To provide a power storage device in which a negative electrode protective film is thin and which can exhibit high battery characteristics.SOLUTION: There is provided a power storage device including a very thin negative electrode protective film having a film thickness of 0.2-19 μm. In a coating liquid for the negative electrode protective film which contains a polymer, a lithium salt compound, and a solvent, ethylene glycol dimethyl ether and/or diethylene glycol dimethyl ether is used as the solvent.SELECTED DRAWING: None 【課題】負極保護膜の厚さが薄く、高い電池特性を発揮することが可能な蓄電デバイスを提供する。【解決手段】膜厚０．２～１９μｍの非常に薄膜の負極保護膜を備える蓄電デバイスを提供する。ポリマー、リチウム塩化合物、溶媒を含有する負極保護膜用コーティング液において、エチレングリコールジメチルエーテル、及び／又はジエチレングリコールジメチルエーテルを溶媒として用いる。【選択図】なし
