The present invention prevents ink leaked from an atmospheric pressure introducing port of an ink cartridge from adhering to an outer surface of the ink cartridge. An ink filling unit includes a leaked ink leading member which receives ink leaked from an atmospheric pressure introducing port and leads the ink to an ink absorber assembled to the outside of a cartridge casing. Due to such a constitution, the ink leaked from the atmospheric pressure introducing port is led to the outside of the cartridge casing by the leaked ink leading member and the ink is absorbed by the ink absorber. Accordingly, it is possible to prevent the ink leaked from the atmospheric pressure introducing port from adhering to an outer surface of the ink cartridge.
