<p>This invention relates to an electrode material for an aluminum electrolytic capacitor that does not require an etching process and that affords improved bending strength and volumetric efficiency of electrostatic capacitance, and a method for producing the same. Specifically, the present invention provides an electrode material for an aluminum electrolytic capacitor, comprising, as constituent elements, a sintered body of a powder of at least one member selected from the group consisting of aluminum and aluminum alloys, and an aluminum foil substrate supporting the sintered body thereon, wherein (1) the powder has an average particle size D 50 of 0.5 to 100 µm, (2) the sintered body is formed on one surface or both surfaces of the aluminum foil substrate and has a total thickness of 10 to 1,000 µm, (3) the porosity of the sintered body is 35 to 49% by volume, and (4) the sintered body is obtained by applying a rolling process to a film made from a composition comprising a powder of at least one member selected from the group consisting of aluminum and aluminum alloys, and subsequently sintering the film.</p> |
