PURPOSE: An ink cartridge is provided to make complex paths such as an ink path and an atmosphere path more easily. CONSTITUTION: In an ink cartridge, an opening of an ink flow groove(35) and an opening of an atmosphere communication recess(36) are formed in the front surface of a container main body, and sealed by a film(57), thereby constituting flow paths. Therefore, a molding die is designed and installed easily and the production cost of the ink cartridge is reduced.
