Abstract

The present invention provides an electrode material for aluminum electrolytic capacitors, the electrode material being capable of exhibiting a high capacitance required for capacitors and having suppressed equivalent series resistance (ESR), and provides a method for producing the electrode material. The present invention provides an electrode material for aluminum electrolytic capacitors, comprising a sintered body of an aluminum alloy powder on at least one surface of a substrate, wherein the substrate is an aluminum foil substrate or an aluminum alloy foil substrate, and the aluminum alloy powder contains Fe in an amount of 2 to 499 mass ppm.
