Abstract
A battery separator includes a porous base material and a heat-resistant layer. The porous base material includes a first surface, a second surface opposed to the first surface, and a hole. The hole is formed in the porous base material and causes the first surface and the second surface to communicate with each other. The heat-resistant layer is configured to cover at least the first surface and a surface of the hole. The heat-resistant layer is formed of an inorganic material and deposited by an atomic layer deposition method.
