Abstract
A laminated body of the present invention 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, the laminated body satisfying 0≦(A)−(B)≦20 mN/m, where (A) represents the critical surface tension over the outermost surface of the porous layer, and (B) represents the critical surface tension that, in a case where the porous layer has been peeled from the laminated body at an interface with the porous film, the porous film has on the side of the interface.
