Abstract
Provided is a liquid storage pack including: a flat flexible bag member storing a liquid to be supplied to a liquid ejection apparatus; and a spacer member provided inside the bag member. The spacer member has an outer shape that is symmetrical with respect to a predetermined reference plane, and is disposed such that, in a state where the bag member is fully filled with the liquid, the reference plane is offset from a center plane of the bag member in a thickness direction of the bag member, the center plane passing a center of the bag member in the thickness direction and being perpendicular to the thickness direction. This liquid storage pack can stably supply the liquid therein at a uniform concentration.
