Claim:
A hollow fiber membrane module unit comprising: a plurality of hollow fiber membrane modules each comprising: a sheet-form hollow fiber membrane ( 1 ) including a hollow fiber membrane having a non-porous layer; and an anchoring member ( 2 ), wherein an end of a side of a hollow fiber membrane opening of the sheet-form hollow fiber membrane ( 1 ) is fastened by the anchoring member ( 2 ) so that a plurality of sheet-form hollow fiber membranes ( 1 ) are substantially parallel to each other while leaving the end open, an end face of the anchoring member ( 2 ) on a side where the hollow fiber membranes are exposed is substantially rectangular, and an end face of the anchoring member ( 2 ) on a side where the hollow fiber membranes open is substantially circular, and wherein a plate member ( 5 ) having a hole through which at least a part of an anchoring member ( 2 ) passes is provided on a side surface of the hollow fiber membrane modules perpendicular to sheet surfaces of sheet-form hollow fiber membranes ( 1 ), and the plate member ( 5 ) is fastened between the anchoring member ( 2 ) and a water collecting cap ( 6 ).
