Zusammenfassung:	A liquid container is provided which can prevent a leakage of liquid from an air introduction portion under any environment of use and storage and which can maintain a stable negative pressure characteristic irrespective of a degree of liquid consumption. The liquid container includes a liquid containing portion (12), a liquid supply portion to supply liquid from the liquid containing portion to a liquid using portion, a valve chamber (30) having a one-way valve which permits a gas introduction into the liquid containing portion and prevents the liquid and gas from getting out of the liquid containing portion, a communication path (13) to communicate the liquid containing portion with the valve chamber, a mechanism having a function of maintaining a volume of the liquid containing space, and a communication path closing member (55) capable of enabling or disabling a communication between the liquid containing portion and the valve chamber through the communication path.
