Abstract
An object of the present invention is to provide a method for manufacturing an aluminum plate which is simple, is high in productiveness, allows the use of arbitrary aluminum materials, and can be suitably used for collectors having excellent adhesiveness to active material layers, a collector for a storage device, and a storage device. The method for manufacturing an aluminum plate of the present invention is a method for manufacturing an aluminum plate having an aluminum substrate having a plurality of through holes in a thickness direction, including an oxidized film-forming step of forming an oxidized film by carrying out an oxidized film-forming treatment on a surface of the aluminum substrate having a thickness in a range of 5 μm to 1,000 μm and a through hole-forming step of forming through holes by carrying out an electrochemical dissolution treatment after the oxidized film-forming step.
