<p>PURPOSE: A composite membrane is provided to facilitate handling by giving excellent mechanical property to anode oxidation nano-porous oxide ceramic films and to enhance resistivity for heat and mechanical shock during back washing caused by high temperature or low temperature pulse gas and thermal expansion. CONSTITUTION: A composite membrane comprises metal mesh and anode oxidation nano porous metal oxide separation films. A manufacturing method of a composite membrane comprises the following steps: making thin plate shaped patterned or non-patterned valve metal into a composite panel by laminating with plate shaped metal mesh; making the composite panel into other shape including cylinder by using the composite panel; and anode oxidizing and etching the same.
