The present invention provides an electrode material for an aluminum electrolytic capacitor, which does not require any etching treatment and which has improved bending strength. Specifically, the present invention provides an electrode material for an aluminum electrolytic capacitor, which comprises, 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 that supports the sintered body thereon, which is characterized in that (1) the powder has an average particle size D50 of 0.5 to 100μm, (2) the sintered body is formed on one surface or both surfaces of the aluminum foil substrate and has a total thickness of 20 to 1,000μm, and (3) the aluminum foil substrate has a thickness of 10 to 200μm and an Si content of 10 to 3,000 ppm. |
