Abstract
A cartridge mountable on a liquid ejection device is provided. The liquid ejection device includes a mounting section, an air supplying portion including an air supplying passage, and a detection section configured to detect an error when a predetermined air pressure is not reached even if air is supplied from the air supplying portion. The cartridge includes a case including a communication portion and a first leakage limiting portion that limits leakage of air supplied from the air supplying portion into an atmosphere. The communication portion includes a second leakage limiting portion that limits leakage of the air supplied from the air supplying portion into the case through the communication portion.
