Abstract: A liquid containing member that can supply a liquid having a uniform concentration of a precipitating component to a liquid ejecting portion is provided. A liquid containing member includes: a liquid containing portion that can contain ink; a liquid supply port for supplying the ink contained in the liquid containing portion to a liquid ejection head; and a communication channel that is in communication with the liquid containing portion and the liquid supply port. The communication channel has a first end that is positioned at a lower end on the gravity direction side in the liquid containing portion and can suck the ink, and a second end that is positioned closer to the anti-gravity direction side than the first end is, and can suck the ink, in an in-use state in which the ink is supplied from the liquid supply port to the liquid ejection head.
