摘要： A spiral-type separation membrane element is provided that can reduce the pressure loss caused by the transmitted water flow within a water-collecting tube without changing the outer diameter and the inner diameter of the water-collecting tube. In a spiral-type separation membrane element in which a separation membrane, a feed-side flow passageway member, and a permeate-side flow passageway member are wound in a spiral form around a porous water-collecting tube in a laminated state, the characteristic feature lies in that said feed-side flow passageway member 2 includes a net-constituting thread 2a in a direction tilted relative to a feed solution flow direction; the net-constituting thread 2a has a cross-sectional part such that a thread diameter X in a direction parallel to a feed solution flow plane is larger than a thread diameter Y in a direction perpendicular to the feed solution flow plane; and a central part P1 between intersection parts of the net-constituting thread 2a is made to have a thread diameter Y smaller than that of an intersection part P2.
