Abstract: According to the present invention, it is possible to obtain a separation membrane element which has an element configuration having high fresh water production performance and high removal performance, has an improved membrane surface linear velocity whereby fouling due to hardly-soluble salts (scales) or organic matters is less likely to occur on the membrane surface particularly in high recovery ratio operation, and is excellent in fresh water production performance and removal performance over a long period of time.

Abstract: A semipermeable composite membrane that reduces an environmental load, and a method of producing the semipermeable composite membrane. A semipermeable composite membrane includes, on a porous support, a semipermeable membrane containing a crosslinked polyamide and a cellulose nanofiber. A method of producing the semipermeable composite membrane includes obtaining a mixed solution containing the cellulose nanofiber, water, and an amine component, and obtaining the semipermeable composite membrane by making the mixed solution be in contact with the porous support, thereafter, causing a cross-linking reaction of the amine component in the mixed solution, with the amine component adhering to the porous support.
