<p>This method for manufacturing a porous aluminum foil is characterized in comprising: forming a porous aluminum coating on the surface of a substrate by electrolysis using a plating solution including at least (1) a dialkyl sulfone, (2) an aluminum halide, and (3) a nitrogen-containing compound and having a water content of 100-2000 ppm; and subsequently peeling the coating from the substrate. The nitrogen-containing compound is preferably at least one species selected from the group consisting of an ammonium halide, a hydrogen halide salt of a primary amine, a hydrogen halide salt of a secondary amine, a hydrogen halide salt of a tertiary amine, and a quaternary ammonium salt represented by the general formula: R1R2R3R4N.X (wherein R1 to R4 may be the same or different and represent an alkyl group, and X represents a counteranion for the quaternary ammonium cation).</p> |
