Zusammenfassung:Provided is an adsorption member excellent in adsorption ability for a foulant having a relatively small molecular weight. The adsorption member includes a plurality of flow channels through which water to be treated passes, and partition walls that partition the flow channels from one another. The partition walls each include a porous ceramic substrate having a communication holes that allow the water to be treated to pass between the adjacent flow channels, and a layer made of particles of a metal oxide fixed to surfaces of the flow channels and surfaces of the communication holes. In the partition walls, a ratio (B/A) of a total pore specific surface area B of pores having a diameter of 6 nm or more and 10 nm or less as measured using a mercury intrusion method to a total pore specific surface area A of pores having a diameter of 1 nm or more and 100 nm or less as measured using a gas adsorption method is 49.3% or more.
