    Abstract: A separation membrane has a porous substrate and a porous resin layer on at least one surface of the porous substrate and the porous resin layer contains a resin. Part of the resin permeates through the porous substrate to form a composite layer. At least one of the following relationships (1) and (2) is satisfied: (1) the porous resin layer has an average pore size in the range of 0.01 to 0.2 mu m and a standard variation of the pore size of 0.1 mu m or less at the surface, and (2) the porous resin layer has macrovoids having short diameters of 0.05xA or more wherein A represents the thickness of the porous substrate, and the rejection of micro particles having an average particle size of 0.9 mu m is at least 90%. This separation membrane can be readily produced by a method for making a separation membrane according to the present invention.

    Abstract: This separation membrane element has a water collection tube and a separation membrane leaf of which a plurality of sheets are stacked and wound around the periphery of the water collection tube. The separation membrane leaf is provided with a sheet that is configured by causing separation membranes, which are provided with a supply-side surface and a permeation-side surface, to be such that the supply-side surfaces face each other, a protrusion being adhered between the permeation-side surfaces of overlapping separation membrane leaves. Of the protrusion, the maximum height and minimum height have a ratio that is 1.10 to 1.50 inclusive, the variation coefficient is 0.02 to 0.15 inclusive, and the degree of impregnation of the protrusion in the sheet is 10-100% inclusive.
