Abstract: A print liquid cartridge comprising a print liquid chamber, print liquid supply portion, a stopper, and a release member. The print liquid supply portion establishes a communication between an interior of the print liquid chamber and an exterior of the print liquid chamber.

The release member releases the stopper, such that the printing-liquid cartridge is permitted to move in a direction opposite to the fluid outflow direction. The stopper is aligned with the release member in a height direction orthogonal to the liquid communication direction and a width direction.
