PROBLEM TO BE SOLVED: To provide a module for pore diffusion membrane separation capable of maximally utilizing fluidizing fractionation effect in which a utilizing membrane is a flat porous membrane.MEANS FOR SOLVING THE PROBLEM: A module for pore diffusion membrane separation is characterized by that: all of wall surfaces in a pore diffusion region existing along the flow passage of a processing object liquid are constituted by porous flat membrane surfaces; the shape of the cross section of the flow passage vertical in a flow passage direction of a membrane is circular; a wall is a flat membrane molded to be cylindrical; and the surface of the flat membrane forms the surface of the wall and has at least one support being in close contact with the external surface (that is, the rear surface of the flat membrane) of the wall and extending in the flow passage direction.SELECTED DRAWING: Figure 1 【課題】流動分別効果が最大限に利用できる孔拡散膜分離用モジュールを提供する。利用される膜は平膜の多孔膜である。【解決方法】被処理対象液の流路に沿って存在する孔拡散領域の壁面がすべて多孔性の平膜表面で構成され、かつ該膜の流路方向に垂直な該流路の断面の形状が円形であり、かつ該壁が円筒状に成型された平膜であり、かつ平膜の表面が該壁の表面を形成し、かつ該壁の外表面（すなわち該平膜の裏面）に密着して流路方向に延びる支持体を少なくとも１個ゆうすることを特徴とする孔拡散分離用モジュール。【選択図】図１
