Abstract:
A heat-resistant insulating layer-provided separator includes a polyolefin layer and a heat-resistant insulating layer formed on one or both surfaces of the polyolefin layer and containing a heat-resistant resin and an oxidation-resistant ceramic particle. The heat-resistant insulating layer contains the oxidation-resistant ceramic particle in a proportion of from 60 to 90%.
