Abstract:
Provided is a lithium secondary battery separator including a stack body of a substrate and a porous heat-resistant polyimide film which covers at least one surface of the substrate. The porous heat-resistant polyimide film has pores which are regularly arrayed three-dimensionally and a film thickness of 5-20 µm.
