PROBLEM TO BE SOLVED: To provide a porous laminate good in resistance to a mechanical load such as bending stress while maintaining its characteristics by a porous structure.SOLUTION: Provided is a porous laminate 1 comprising: an A layer 1a as a porous film provided on a supporting body 2 and having a polymer nanofiber 3; and a B layer 1b as a porous film provided on the A layer 1a and having a polymer nanofiber, in which the abundance ratio of the polymer nanofiber 3 included in the A layer 1a is higher than the abundance ratio of the polymer nanofiber included in the B layer 1b, and a difference between the abundance ratio of the polymer nanofiber 3 included in the A layer 1a and the abundance ratio of the polymer nanofiber included in the B layer 1b exceeds 40%.SELECTED DRAWING: Figure 1 |
