摘要： A spiral wound type separation membrane element (1) includes a spiral wound type membrane component formed by superposing separation membranes (2) of membrane materials supported on nonwoven fabric members on both surfaces of a permeated liquid passage forming member (3) and bonding three sides with an adhesive thereby defining an envelope-like membrane (4), mounting an opening of the envelope-like membrane (4) on a water collection pipe (5) and bonding the same with an adhesive and spirally winding the envelope-like membrane (4) around the outer peripheral surface of the water collection pipe (5) along with a raw liquid passage forming member (6). The outer peripheral surface of the envelope-like membrane (4) forming the spiral wound type membrane component (1) is covered with a sheath member (10), and anti-telescopic members (11a,11b) are mounted on both end surfaces of the envelope-like membrane (4) respectively. Each of the aforementioned components forming the spiral wound type separation membrane element (1) is made of heat-resistant alkali-resistant plastic.
