；。However, all of these have smooth surfaces from a macroscopic perspective, so in order to prevent concentration polarization and gel layer formation at the time of treatment, the surface speed of the liquid to be treated should be increased! Stiffness or turbulence promoting materials are inserted. Therefore, a high flow rate is required, a large-capacity pump is required, and the turbulence promoting material may damage the piping. In addition, since these membrane separation elements have a limited processing surface and area per unit volume, it is inevitable that the equipment will become larger.

This plate-shaped body is further provided with a large number of through holes substantially parallel to each other in each portion corresponding to the peaks of the cross section. Preferably, a large number of through holes are bored in the portion corresponding to the valley of the cross section. In a membrane module formed by assembling membrane separation elements, the through holes allow the liquid to be processed to flow in a cross direction across each layer of the membrane separation elements, thereby increasing the effect of promoting turbulent flow. It is desirable to provide a large number of round holes as the through holes, especially from the viewpoint of reinforcing the strength.
