PROBLEM TO BE SOLVED: To provide a fastening structure of flat membrane elements, capable of simplifying the structure and preventing the occurrence of a failure such as water leakage due to the breakage of a water collection part or the like by integrally fastening the flat membrane elements and collecting filtrate water. SOLUTION: In the fastening structure of the flat membrane elements, the plurality of flat membrane elements A configured by bonding the peripheral edge of a membrane sheet 1 to at least one surface of a support plate 2 and provided with a discharge port 3 for discharging the filtrate water filtered by the membrane sheet 1 formed on the support plate 2 are laminated. The discharge port 3 is formed so as to pass through in the laminating direction of the laminated flat membrane elements A, a tubular fastening member 5 comprising a pipe member 51A is inserted into the discharge port 3, and the laminated flat membrane elements A are fastened by a nut member 52 disposed at the end part of the fastening member 5.
