    Abstract: The present invention relates to a separation membrane element including: a separation membrane; and a permeate-side channel material disposed on a permeate side of the separation membrane, wherein the permeate-side channel material is a rugged sheet object having a recess and a protrusion on at least one face thereof, the rugged sheet object is composed of a porous region formed of a through-hole in a thickness direction of the rugged sheet and a non-porous region other than the porous region, and a rate of a number of the through-hole in the recess of the rugged sheet object to a total number of the through-hole present in the rugged sheet object is 80% or more.

    Abstract: A core-sheath composite cross-section fiber, wherein the core section polymer is a thermoplastic polymer, the sheath-section polymer is a polyamide having a dicarboxylic acid unit having a sebacic acid unit as a main component, the boiling-water shrinkage ratio is 6.0-12.0%, and the stress per unit fineness during 3% elongation in a fiber tensile test is 0.60 cN/dtex or more. The core-sheath composite cross-section fiber has excellent moisture-absorbing capability and wrinkling prevention, and the moisture-absorbing capability is maintained even when washed.

    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.
