Abstract
A sealer holding member for a membrane element is disposed at an end of a spiral-type membrane element on an outer circumference thereof, and allows a feed to flow into a membrane end of the membrane element. The sealer holding member includes a first annular portion, an annular projection, a second annular portion, and a third annular portion arranged in this order. The first annular portion is engaged with an outer-covering member for the membrane element and receives an end of the membrane element without contacting a side of the membrane element. The second annular portion receives a sealer on an outside thereof.
