ABSTRACT:
An object of the present invention is to provide a spiral membrane element that can form a uniform fiber reinforcement layer on an outer circumferential surface by a simple process without a great change in the materials, as well as a process for producing the same. The spiral membrane element of the present invention is a spiral membrane element which is provided with a cylindrical roll R in which a separation membrane, a feed-side flow passageway member, and a permeate-side flow passageway member3are spirally wound in a laminate state around a perforated center tube5and in which a sealing part for preventing mixing of feed-side fluid and permeate-side fluid is disposed, wherein at least one sheet of the permeate-side flow passageway member3has a fiber cloth23aextended or connected to the outer circumferential side, and the fiber cloth23ais wound around an outer circumference of said cylindrical roll R, impregnated with a resin and hardened to thereby form a fiber reinforcement layer.
