description Provided is a separator for non-aqueous batteries, capable of being usefully used in non-aqueous batteries, and a non-aqueous battery equipped with this separator. The separator for non-aqueous batteries includes: a base layer comprising a fiber aggregate, and an electrolyte-swellable resin layer formed on at least one surface of the base layer, the resin layer comprising a urethane resin (C) obtained by reacting a polyol (A) including a vinyl polymer (a1) and a polyether polyol (a2) with a polyisocyanate (B). The vinyl polymer (a1) has as a main chain a vinyl polymer (a1') having two hydroxyl groups at one of the termini of the main chain, and a polyoxyethylene chain having a number average molecular weight of 200 to 800 as a side chain, the percentage of the polyoxyethylene chain based on the vinyl polymer (a1) being within the range of 70 mass% to 98 mass%.
