Abstract (en)
A manufacturing method of an ink cartridge is simplified, wherein the ink cartridge is capable of preventing ink from being damaged in its degassed properties. The ink cartridge is provided with: an ink chamber (2) filled with a foam member (8); an ink supply port (4); a pressure reducing port (3); a pair of lids (12a, 12b), wherein an atmosphere communication port (5) is formed so as to pass through the lids (12a, 12b); and, a sealing member (7a) for sealing the atmosphere communication port (5) shut. A resilient element (6) is inserted into each of the ink supply port (4) and the pressure reducing port (3). The sealing member (7a) is made of material which is impermeable to both gases and water vapor. <IMAGE>
