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: The present invention relates to a separation membrane element including a supply-side channel member, in which: the supply-side channel member has a net shape in which plural fibrous rows X including fibrous objects A and plural fibrous rows Y including fibrous objects B cross each other sterically to form intersections; at least one of the fibrous objects A and the fibrous objects B have a large diameter portion and a small diameter portion along a longitudinal direction; at least one of the fibrous objects A and the fibrous objects B include a thread that is thinner at a central portion located between intersection portions than at the large diameter portion; and a fiber between an arbitrary intersection and an adjacent intersection is a tapered fiber whose diameter increases like a taper in a direction from one intersection to the other intersection.
