An extrusion mold for molding a ceramic membrane having an one-end closed tube structure which is easily integrated and has a high gas separation efficiency, and a fabrication method of a ceramic membrane tube using the same, the extrusion mold comprised of an outer mold, an inner mold and an extrusion hole end cap, wherein the cap has a through hole at its center for controlling an extrusion molding density, and a passage is formed in each of the inner and outer molds for maintaining an inner pressure of an extruded tube to be the same as an outer pressure. The one-end closed ceramic membrane tube is fabricated by supplying a ceramic mixture into the extrusion mold in a state that the end of the extrusion hole of the extrusion mold is closed by the cap, removing the cap after filling the mixture in the end of the extrusion hole, and further supplying the mixture into the extrusion mold to obtain a tubular ceramic extrusion body with a particular length.
