Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a separator of a low basis weight excellent in tensile strength and water absorption whose elution component amount to a formation liquid is small.SOLUTION: The separator for an electrolytic capacitor includes at least one kind of resin selected from a polyester resin, an epoxy resin, and a urethane resin, having a polyethylene glycol chain and a carboxyl group. A polyethylene glycol content of the resin is greater than or equal to 30 mass% and less than or equal to 60 mass%.SELECTED DRAWING: None 【課題】低坪量であって、かつ引張強さ、吸水性に優れ、化成液に対する溶出成分量が少ないセパレータを提供することを目的とする。【解決手段】ポリエチレングリコール鎖及びカルボキシル基を有する、アクリル樹脂、ポリエステル樹脂、エポキシ樹脂、ウレタン樹脂からなる群より選択される少なくとも1種の樹脂を含み、前記樹脂は、ポリエチレングリコール鎖含有量が３０質量％以上６０質量％以下である電解コンデンサ用セパレータを提供する。【選択図】なし
