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 heat treatment step in which the aluminum-coated resin molded body is subjected to heat treatment at a temperature equal to or higher than 270° C. and lower than 660° C. to decompose the resin molded body.
