摘要

By providing a first conductive porous layer containing a conductive carbon material and a modified polyolefin resin, it is possible to provide a gas diffusion layer to be used in a battery and which suppresses crushing of the pores in the conductive porous layer and exhibits strong adhesion between a separator and a conductive porous substrate.
