摘要：
A spiral separation membrane element includes a water collection tube; a separation membrane wound around the water collection tube, having a feed-side surface and a permeate-side surface, and including a band-shaped region on at least one end of the feed-side surface in an axial direction of the water collection tube; and a channel material fused to the band-shaped region.
