Abstract: PURPOSE: The manufacturing method of a nano porous alumina separation film having the straight pipe through-hole of a nano size diameter in which both ends are opened is provided to reduce the manufacturing cost and process time of a separation film by simplifying a manufacturing process. CONSTITUTION: The manufacturing method of a nano porous alumina separation film having the straight pipe through-hole of a nano size diameter in which both ends are opened performs the anode oxidation until an aluminum material for the anode oxidation all disappears after washing and electrolytically polishing the aluminum material. The anode oxidation uses a one-step anode oxidation method, a two-step anode oxidation method, or an imprint method. If the aluminum material is an aluminum board, the anode oxidation is performed to the bottom surface of the aluminum board in case the anode oxidation is performed from top to down and the anode oxidation is performed to the top surface of the aluminum board in case the anode oxidation is performed from bottom to top. If the aluminum material is a hallow cylinder, the anode oxidation is performed to the inner surface in case the anode oxidation is performed from the outer surface of the hallow cylinder to the inside and the anode oxidation is performed to the outer surface in case the anode oxidation is performed from the inner surface of the hallow cylinder to the outside.
