    摘要： To provide a gas diffusion layer excellent in micro short-circuit resistance and anti-flooding characteristics by optimizing the surface shape of a gas diffusion layer.In a gas diffusion layer for a gas diffusion electrode including at least a catalyst layer containing an electrode catalyst and a gas diffusion layer having electron conductivity and gas diffusibility, a second surface of the gas diffusion layer, which is positioned opposite to a first surface thereof to be in contact with the catalyst layer, is made rougher than the first surface. The first surface has a maximum height Ry1 of 10 to 50 determined by JIS B 0601 surface roughness measurement method, and the second surface has a maximum height Ry2 of 100 to 500 determined by JIS B 0601 surface roughness measurement method.
