One end of the rectangular plate-shaped membrane support has an opening on the surface of the membrane support, and the other end forms a filtered water flow passage communicating with the filtered water suction pipe. Then, a membrane sheet is provided to cover the surface of the membrane support. Here, the membrane sheet means an organic filtration membrane or a non-woven fabric or the like on which an organic filtration membrane is formed. When performing the treatment, the water to be treated is filtered by the organic filtration membrane by immersing the membrane module in the to-be-treated water in the tank and applying a negative pressure to the passage of the treated water through the filtered water suction pipe. .

As shown in the cross-sectional view of FIG. 1 and the plan view of FIG.
A fusion rod 6 is circumferentially arranged on the membrane support 4 along the periphery thereof, and a membrane sheet 5 is arranged so as to cover the fusion rod 6. When manufacturing a membrane module, an ultrasonic fusing roller is run over the membrane sheet 5 in this state. Then, as shown in FIG. 3, the fusion rod 6 is melted, and the membrane support 4 and the membrane sheet 5 are fused at the location of the fusion rod 6. With this configuration, the melting of the membrane support 4 is prevented, and the membrane sheet 5 is securely attached to the membrane support 4 without deformation around the fused portion of the membrane support 4 and deformation of the membrane sheet 5 accompanying the deformation. Can be fixed. At this time, the membrane sheet 5
Since the film itself is not deformed, a membrane module having high strength can be obtained. Further, by replacing the membrane sheet 5, the membrane support 4 can be reused.
