Abstract
Provided is a method of producing an aluminum structure using a porous resin molded body having a three-dimensional network structure, with which it is possible to form an aluminum structure having a low oxide content in the surface of aluminum (i.e., having an oxide film with a small thickness), and in particular, it is possible to obtain an aluminum porous body that has a large area. The method includes a step of preparing an aluminum-coated resin molded body in which an aluminum layer is formed, directly or with another layer therebetween, on a surface of a resin molded body composed of urethane, and a step of decomposing the resin molded body by bringing the aluminum-coated resin molded body into contact with concentrated nitric acid with a concentration of 62% or more.
