Abstract
Provided is a laminate which is capable of ensuring a high level of safety by preventing an internal short circuit due to, for example, breakage of a non-aqueous electrolyte secondary battery while maintaining various performance capabilities of the non-aqueous electrolyte secondary battery. A laminate (10) includes: a porous film containing polyolefin as a main component; and a porous layer containing fine particles; the porous layer being laminated to at least one side of the porous film, in an electrical conduction test by nail penetration in which test a displacement in a thickness direction of the laminate (10) during a period from when a dielectric breakdown occurs in the laminate (10) to when the laminate (10) is brought into electrical conduction is measured by use of a nail (2) of N50 specified in JIS A 5508 and under a condition in which the nail (2) descends at a descending speed of 50 μm/min, the displacement being not less than 20 μm and not more than 200 μm.
