PROBLEM TO BE SOLVED: To provide a separator for aqueous electrolyte power storage devices which is high in the affinity with an aqueous electrolyte, and suitable for prevention of the short circuit between electrodes.SOLUTION: A separator for aqueous electrolyte power storage devices comprises: a three-dimensional mesh-like skeleton formed by an epoxy resin; and pores communicated with one another so as to allow ions to travel between a top surface of the separator and the rear surface thereof. The separator has a thickness in a range of e.g. 5-50 μm. The separator can be produced by e.g. removing porogen from an epoxy resin sheet. 【課題】水系電解液との親和性が高く、電極間の短絡の防止に適した水系電解質蓄電デバイス用セパレータを提供する。【解決手段】エポキシ樹脂で構成された三次元網目状骨格と、セパレータの表面と裏面との間でイオンが移動できるように連通している空孔と、を備えた、水系電解質蓄電デバイス用セパレータとする。セパレータの厚さは、例えば５〜５０μｍの範囲とする。このセパレータは、例えば、エポキシ樹脂シートからポロゲンを除去することにより製造することができる。【選択図】図１
