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.
