A liquid container from which a liquid is capable of being supplied to a liquid ejecting head in a liquid ejecting apparatus, the liquid container comprising: a liquid storage body that stores the liquid; and a case that stores the liquid storage body; wherein the liquid storage body has a liquid storage section formed like a bag by joining edges of opposing films together, and a liquid supply section configured to supply the liquid from an interior of the liquid storage section to an outside of the liquid storage section, in a state in which the liquid storage section is filled with the liquid and the liquid storage body is installed in the liquid ejecting apparatus, at least part of an upper edge of the liquid storage section and at least part of a lower edge of the liquid storage section are in contact with the case and a first inner surface of the liquid storage section and a second inner surface of the liquid storage section, the second inner surface being opposite to the first inner surface, are mutually separated, and the liquid storage section is structured so that as the liquid is supplied, the first inner surface and the second inner surface gradually come close together and, at the same time, come into mutual contact from top to bottom, forming, at a bottom of the interior of the liquid storage section, a liquid flow path through which the liquid flows from the liquid storage section to the liquid supply section, characterized in that both the upper edge and lower edge of the liquid storage section are bent so as to face in a direction toward which the first inner surface is curved, and the second inner surface approaches the first inner surface along with supply of the liquid while drawing an arc so as to follow the first inner surface. a liquid storage body that stores the liquid; and a case that stores the liquid storage body; wherein the liquid storage body has a liquid storage section formed like a bag by joining edges of opposing films together, and a liquid supply section configured to supply the liquid from an interior of the liquid storage section to an outside of the liquid storage section, a liquid storage section formed like a bag by joining edges of opposing films together, and a liquid supply section configured to supply the liquid from an interior of the liquid storage section to an outside of the liquid storage section, in a state in which the liquid storage section is filled with the liquid and the liquid storage body is installed in the liquid ejecting apparatus, at least part of an upper edge of the liquid storage section and at least part of a lower edge of the liquid storage section are in contact with the case and a first inner surface of the liquid storage section and a second inner surface of the liquid storage section, the second inner surface being opposite to the first inner surface, are mutually separated, and the liquid storage section is structured so that as the liquid is supplied, the first inner surface and the second inner surface gradually come close together and, at the same time, come into mutual contact from top to bottom, forming, at a bottom of the interior of the liquid storage section, a liquid flow path through which the liquid flows from the liquid storage section to the liquid supply section, characterized in that both the upper edge and lower edge of the liquid storage section are bent so as to face in a direction toward which the first inner surface is curved, and the second inner surface approaches the first inner surface along with supply of the liquid while drawing an arc so as to follow the first inner surface.
