There is provided a method of producing an aluminum structure using a porous resin molded article having a 3-dimensional network structure capable of forming a low-oxide aluminum structure in the surface of aluminum (ie, having an oxide film of small thickness) In particular, it is possible to obtain a porous aluminum body having a large area. The method comprises a step of producing an aluminum-coated resin molded article in which an aluminum layer is formed, directly or with another layer therebetween, on a surface of a resin molded article composed of urethane and a step of decomposing the resin molded article by impregnating the aluminum-coated resin molded article concentrated nitric acid having a concentration of 62% or more is contacted. |
