1. A liquid container for supplying a liquid to an ink jet head, comprising the liquid container:
a liquid storage portion configured to store the liquid;
a deformable flexible member constructing a part of the liquid storage portion;
a planar member disposed inward the liquid storage portion and in contact with the flexible member; and
an elastic member, a part of the elastic member being fixed to the planar member, biasing the liquid storage portion in an expanding direction so as to have the inside of the liquid storage portion be in a negative pressure state,
wherein the planar member includes a hook at a part of the planar member, the hook enabling the elastic member to be in a compressed and deformed state by engaging with a part of the elastic member.
