An object of the present invention is to provide a process of anodizing a long-length aluminum plate, which reduces loss of electricity. Also disclosed is an anodization process of the above plate, employing an anodization apparatus possessing an electrolyte tank, an anode, a cathode and an electric insulator with an opening forming a current flow section, the process possessing the steps of providing the plate between the cathode and the electric insulator; and anodizing the plate by supplying current between the anode and the long-length aluminum plate, wherein the opening is located at a position of at most 10% in width length from an outer side of the plate with respect to the width length of the plate, a part of the plate is brought into contact with a part of the electric insulator, and the plate and the electric insulator travel in uniform speed. |
