Method of producing aluminum structure and aluminum structure

Abstract

A surface of a porous resin body having a three-dimensional network structure can be plated with aluminum at a uniform thickness and thus a high-purity aluminum structure is formed. A method for producing an aluminum structure includes a step of plating a resin porous body, which has a three-dimensional network structure and has a surface that has been made electrically conductive, with aluminum in a molten-salt bath, in which the molten salt is a salt mixture of aluminum chloride and an organic salt and plating is conducted while controlling the temperature of the molten-salt bath to be 45° C. or higher and 100° C. or lower. Preferably, the molten-salt bath further contains 1,10-phenanthroline at a concentration of 0.25 g/l or more and 7 g/l or less.
