PROBLEM TO BE SOLVED: To maintain the negative pressure in a liquid supply path downstream of the one-way valve in an appropriate range by providing a one-way valve in the liquid storage container for supplying a liquid to the outside so as to maintain a stable negative pressure characteristic without leakage of the liquid in any use environment or storage environment, regardless of the liquid consumption stage. SOLUTION: In the liquid storage container comprising a deformable movable member made of at least partially a flexible material with the inside thereof provided as a substantially sealed space for storing a liquid in the sealed space for supplying the liquid to the outside, a one-way valve for allowing passage of a liquid or a gas from the liquid storage container to the outside, or from the outside to the liquid storage container, is provided.
