Abstract
A separator includes a base material and insulating layers. The insulating layers are on both surfaces (first surface and second surface) of the base material. Each active material layer has a thickness equal to or less than 60 μm. A ratio of the thickness of the insulating layer (a total of the thickness of the insulating layer on the first surface of the base material and the thickness of the insulating layer on the second surface of the base material) to the thickness of the base material is equal to or greater than 1.50 and equal to or less than 3.00.
