PURPOSE: An ink cartridge is provided to allow the ink cartridge to be adapted for a small-sized color ink cartridge by installing a pressure adjusting module having a compact size in the ink cartridge. CONSTITUTION: An ink cartridge(100) includes an ink storing section(110), a cover(111) for covering the ink storing section(110), a pressure adjusting module(130) fixed to a lower portion of the cover(111), and a print head(150) for discharging ink in a liquid droplet-phase. The ink storing section(110) is divided into first and second chambers(114,116) by a partition wall(112). An ink path(113) is formed at a lower portion of the partition wall(112). A filter(152) is provided at a lower portion of the first chamber(114). An ink feeding pipe(154) is formed at a lower portion of the filter(152). The pressure adjusting module(130) is communicated with the ink storing section(110). A guide plate(134) and a coil spring(136) are installed in the pressure adjusting module(130).
