Abstract
A liquid cartridge is provided that supplies liquid to a liquid ejecting apparatus by being mounted in the liquid ejecting apparatus. The liquid cartridge includes a cartridge body having a side face in which an opening is formed; and a flexible film for forming an ink accommodating chamber that is a closed space for accommodating the liquid, with the cartridge body by covering the opening of the cartridge body. The flexible film is caused to deform toward the ink accommodating chamber by atmospheric pressure that acts on the flexible film when the liquid cartridge is got out from a vacuum bag in which the liquid cartridge is packaged, thereby increasing the pressure in the ink accommodating chamber.
