Abstract

See full text

Provided is a porous laminate having satisfactory resistance to a mechanical load such as a bending stress while maintaining the characteristics of a porous structure. A porous laminate includes: a layer A formed on a support, the layer A including a porous film containing polymer nanofibers; and a layer B formed on the layer A, the layer B including a porous film containing polymer nanofibers, in which: an existence ratio of the polymer nanofibers contained in the layer A) is larger than an existence ratio of the polymer nanofibers contained in the layer B; and a difference between the existence ratio of the polymer nanofibers contained in the layer A and the existence ratio of the polymer nanofibers contained in the layer B is more than 40%.
