Abstract
A membrane element 36 includes filtration membranes 45 on the flat part of the membrane element 36. Spacing members 60 keep spacing S between the filtration membranes 45 between the membrane elements 36 when the membrane elements 36 are arranged with the filtration membranes 45 opposed to each other. The spacing members 60 each have spacer sections 61a and 61b that keep the spacing S between the filtration membranes 45 between the membrane elements 36 in the direction of a membrane surface cleaning stream that flows along the surface of the filtration membrane 45.
