Abstract: A membrane unit includes: a cross-flow membrane filter; a cylindrical casing housing the membrane filter; a cap provided with an inflow port that allows water to flow into the casing, a first discharge port that discharges, to outside of the casing, permeated water obtained as a result of water that flows into the casing from the inflow port permeating the membrane filter, and a second discharge port that discharges, to the outside of the casing, concentrated water obtained as a result of water being concentrated as a result of the permeated water permeating the membrane filter, the cap detachably occluding the casing; and a positioning member which is fixed to the cap taking the first discharge port as a reference, and which defines a position of the membrane filter inside the casing.
