PURPOSE: A tubular nanoporous oxide ceramic membrane and a membrane filter using the same are provided to improve filtering efficiency with big porosity comparing to a ceramic filter, and to increase a life span of the membrane. CONSTITUTION: A tubular nanoporous oxide ceramic membrane(100) includes an anode having a cylindrical shape and is made of a metal. A direct penetration hole(110) of nano size is formed on a ceramic wall by anodizing and oxidizing a metal. An external diameter of the nanoporous oxide ceramic membrane is 10 m ~ 20 μm. A thickness of the membrane is 50 mm ~ 10 μm.
