An object of the present invention is to provide an anode oxidation method with higher anodizing rate, less energy consumption and higher efficiency of oxide film formation and to provide an anodizing method in which an excellent, uniform oxide film can be obtained without burning of the metal body even if the metal body has a complicated profile. This invention provides a metal anode oxidation treatment system, which is characterized in that, in the metal anode oxidation process, (A) is disposed with vibration generation mechanism containing vibration motor; a vibration fluidly stirring mechanism coupled with the vibration generation mechanism and one-section or multiple-sections vibration vanes fixed with a vibration rod in the stirring tank vibrating at an amplitude from 0.5 to 3.0 mm and at a vibration frequency of 200 to 800 times per minute; an AC/DC shifter used to control the vibration motor vibrating arbitrarily at 10-500 Hz; and a vibration fluidly stirring device of the treatment bath of the vibration stress distribution mechanism disposed at the connection portion of the vibration generation mechanism and the vibration fluidly stirring mechanism, and (b) is to concurrently perform an aeration in the treatment bath by using air bubbles generated by a ceramic diffuser having a pore diameter of 10 to 400 mum and 30-40% of porosity.
