The conductive porous layer for batteries according to the present invention comprises a laminate comprising a first conductive layer and a second conductive layer. The first conductive layer includes at least a conductive carbon material and a polymer. The second conductive layer includes at least a conductive carbon material and a polymer. The conductive porous layer satisfies at least one of the following two conditions: 'the polymer in the first conductive layer is present with a high density at the surface of the layer in contact with the second conductive layer than at the surface not in contact with the second conductive layer' and 'the polymer in the second conductive layer is present with a higher density at the surface of the layer in contact with the first conductive layer than at the surface not in contact with the first conductive layer.' This makes it possible to provide a conductive porous layer with good adhesion between the first conductive layer and the second conductive layer and with reduced film thickness variation in each conductive layer. The conductive porous layer of the present invention can be used for fuel cells, metal-air batteries, and the like.
