Abstract
An object is to provide a method for manufacturing an aluminum plate having a plurality of through-holes in a thickness direction in which the locations of the through-holes are controlled and a manufacturing apparatus that is used in the method for manufacturing the aluminum plate. A method for manufacturing an aluminum plate of the present invention is a method for manufacturing an aluminum plate having a plurality of through-holes in a thickness direction, the method including a coating-forming step of forming a coating of an aluminum compound on a surface of an aluminum substrate having a thickness of 5 to 1,000 μm, a partial coating removal step of removing, out of the coating, the coating present on portions in which the through-holes need to be formed, and a through-hole-forming step of forming the through-holes in the aluminum substrate by carrying out an electrochemical melting treatment on the aluminum substrate after the partial coating removal step.
