PROBLEM TO BE SOLVED: To simplify configurations of a membrane unit and a membrane unit composite body and improve strength of a filtered water collection member as well as durability and chemical resistance of a connection part between a filter member and the filtered water collection member.SOLUTION: A membrane unit 1 includes a plurality of parallel-arranged membrane modules 4, each including a filter member 2 and a filtered water collection member 3. The filtered water collection member 3 discharges from upper and lower ends thereof solid-liquid separation water taken from the filter member 2. A group of the filtered water collection members 3 at both ends of the membrane unit 1, each including a connection part between the filtered water collection member 3 and the filter member 2, is coat-molded by a coating material 5. A composite body of the membrane unit 1 is formed by laminating the membrane unit 1. |
