Abstract
An end member (A) for a spiral separation membrane element includes: an inner annular portion (); an outer annular portion () surrounding the inner annular portion () at a distance from the inner annular portion (); a plurality of connecting portions () connecting the inner annular portion () and the outer annular portion (); and a shield plate () disposed between at least one pair of the connecting portions () and forming an opening () between the shield plate () and the outer annular portion (). According to this configuration, a radially outwardly spreading flow is formed by the shield plate (), and therefore suspended solids in a feed liquid can be effectively directed to the peripheral region.
