Abstract
Disclosed is a membrane separation device comprising a plurality of flat membrane elements (52) arranged in parallel to one another so as to form channels for a solution to be treated therebetween, and a collecting case (59) having a collecting space that is formed internally and communicates with filtrate flow channels of the membrane elements (52). The collecting case (59) includes a membrane element holder (53) having a plurality of slits, into which the sides of respective membrane elements (52) are inserted, and a stopper (58) which abuts on the membrane element holder (53) in the collecting case (59), and a filler (55) is provided in the slits to attach and watertightly seal between the membrane elements (52) and the membrane element holder (53).
