PROBLEM TO BE SOLVED: To improve the performance of an ink cartridge 1 and reduce residual ink in an ink pack 6 by sufficiently stabilizing the supply of ink to a printer. SOLUTION: The ink pack 6 storing ink is stored in a cartridge case 2. The ink pack 6 is structured by joining a plurality of flexible films F in the form of a bag by thermal fusion. A flat plate 8 stiffer than the films F is provided in the reverse portion or the obverse portion of the ink pack 6, and a pressurizing member 10 pressurizing the rear end side of the flat plate 8 more strongly than the tip sides is arranged in the cartridge case 2.
