<p>In order to form at high speed an anodic oxidation film as an insulating layer on one side of a metal substrate, an anodic oxidation device is configured to comprise: a power supply drum (2) that supports through close contact a band-shaped material (1) made from an anodic oxidizable metal or a band-shaped material (1) having at least one surface made from a compound conductive metal foil, which is an anodic oxidizable metal, and a part (2a) where at least the band-shaped material (1) is adhered is made from a conductive material; an opposing electrode (3) disposed facing the power supply drum (2); an electrolysis tank (5) filled with an electrolyte (4) in which the opposing electrode and part of the power supply drum (2) that supports the band-shaped material (1) are immersed; a protective member (6) that is made from a non-conductive material that overlaps the end part in the width direction of the band-shaped material (1), which is closely supported by the power supply drum (2), and the part of the power supply drum to which the band-shaped material (1) is not adhered, thereby protecting these parts from the electrolyte (4); and a drive unit that is synchronized with the circumferential speed of the power supply drum (2), and which forces the protective member (6) and the band-shaped material (1), which is in close contact with the power supply drum (2), to travel together in the electrolyte (4).</p> |
