In an ink pack 24 stored in an ink cartridge 24 of a printer, a first welded portion is formed by bonding both end portions of a sheet of film to each other. A tube-shaped bag portion 31 is formed by the first welded portion. One opening of the bag portion 32 is thermally welded in a state where a supply member 27 is inserted into the film, thereby forming a second welded portion 38. The other opening of the bag portion is sealed through the thermal adhesion, thereby forming a third welded portion 39. The ink volume capable of being stored in the bag portion 31 of the ink pack 24 is larger than the volume in a frame 26c for storing the ink pack 24.
