Provided are: a separator for non-aqueous batteries, which can be utilized usefully for non-aqueous batteries; and a non-aqueous battery equipped with the separator. The separator for non-aqueous batteries comprises a base material layer which is composed of a fiber aggregate and a resin layer which can be swollen with an electrolytic solution and is formed on at least one surface of the base material layer, wherein the resin layer and the base material layer are integrated with each other, the resin layer comprises a urethane resin (C) which is produced by reacting a polyol (A) comprising a vinyl polymer (a1) and a polyether polyol (a2) with a polyisocyanate (B), and the vinyl polymer (a1) contains a vinyl polymer (a1') having two hydroxy groups at one end as the main chain, also contains a polyoxyethylene chain having a number average molecular weight of 200-800 in an amount 70-98 mass% relative to the total amount of the vinyl polymer (a1) as a side chain, and has a number average molecular weight of 2000-7000. |
