Abstract
A first laminated body includes: a porous film containing a polyolefin as a main component; and a porous layer on at least one surface of the porous film, the porous layer containing a resin. A second laminated body includes: a porous film containing a polyolefin as a main component; and a porous layer containing a resin. The laminated body is usable as a secondary battery separator having a higher dielectric strength. A third laminated body is provided in which occurrence of a curl is prevented. A nonaqueous secondary battery separator is provided disposed between a cathode and an anode, the separator including: a porous base material containing a polyolefin as a main component; and a porous layer on at least one surface of the porous base material, the porous layer containing a polyvinylidene fluoride-based resin.
