Abstract

PURPOSE:To provide the subject method comprising impregnating a porous sheet-like material from its both surfaces in a high molecular solution having a semipermeable membrane forming capacity, and embedding the porous sheet-like material in the membrane structure having a gel layer and a skin layer, thereby obtaining a semipermeable flat membrane having a high salt refusing ratio, a high resolution ration and a high water permeabile capacity.
