Abstract
An adsorption structure unit prevents water leakage from an adsorption structure and improves the durability of the adsorption structure and the durability of the adsorption structure unit. An adsorption structure has a filter portion having a plurality of flow paths divided by a plurality of partition walls and a plugged portion shutting a feed water inflow or outflow end of the plurality of flow paths, a water-impermeable outer tube accommodating the filter portion, and a seal material blocking a gap between the filter portion and the outer tube in at least one end portion of the filter portion. An adsorption structure unit has the adsorption structure, a housing supplying feed water from one end of the adsorption structure, and discharging the feed water from the other end, and a ring member disposed between end portions on both sides of the outer tube and an inner surface of the housing.
