To present a membrane element in an immersion type membrane separation apparatus capable of filtering efficiently by holding a uniform filtering capacity on the whole of the membrane surface if clogging occurs in a part of the membrane surface. The membrane element A is composed of a filtration chamber forming part C arrayed by dividing filtration chambers into a plurality in a vertical direction, water collecting transverse groove forming parts B forming transverse grooves () for collecting filtered water from each filtration chamber in a lateral direction by connecting with the filtration chamber forming part C, and a water collecting route () by connecting with the water collecting transverse groove forming parts B for collecting the water flaker in the lateral direction from each transverse groove () and discharging to outside.

A membrane cartridge in an immersion type membrane separation apparatus capable of suppressing vibrations applied to the membrane cartridge by an ascending force of membrane cleaning gas and others by firmly coupling the adjacent membrane cartridges disposed in parallel. In a membrane cartridge in an immersion type membrane separation apparatus, selvages larger in thickness than a membrane cartridge main body are formed at both sides of the membrane cartridge, and a header forming part is formed on one selvage, and a guide hole is formed in other selvage relatively, and the header forming part and the guide hole of the membrane cartridge disposed adjacently by varying the direction mutually are formed to communicate and connect with each other.
