(57) An ink cartridge 7 includes a cartridge main body 71 forming an ink storage chamber, an ink supply port 39 formed in a bottom section of the ink storage chamber for supplying an ink fluid stored in the ink storage chamber to a print head mounted on a carriage of a printer, and a positioning protrusion 87 projectingly provided on a front wall 73 of the cartridge main body 71. The positioning protrusion 87 fits into a positioning groove of the carriage, so that the cartridge main body 71 is positioned at a cartridge mount section of the carriage. The positioning protrusion 87 is formed integrally into a hollow bag structure where a pair of mutually-opposing plate-like sections 87a, 87b are joined together by means of an extremity joint wall 87c and a joint bottom wall 87d.
