Abstract: A liquid cartridge includes: a casing including a liquid chamber; a liquid supply portion; a deformable member; a movable member; and an urging member. An internal pressure of the chamber is reduced as liquid flows out of the chamber. The deformable member protrudes from the casing in a cross direction crossing forward and rearward directions and has an internal space in communication with the chamber. The deformable member has such an elasticity that a dimension thereof in the cross direction becomes smaller as the internal pressure of the chamber is reduced. The movable member includes a detection portion, and a contact portion contacting the deformable member. The contact portion is in contact with the deformable member and disposed at one of positions further forward and further rearward relative to the deformable member. The urging member urges the movable member to move the contact portion toward the deformable member.
