Abstract
An ink cartridge, for an ink jet printer, having a cartridge case, first and second ink bags housed in the cartridge case, and a partition plate placed between the ink bags. The partition plate is dropped into a case main body of the cartridge case through an upper opening of the case main body. When a case lid is attached to the case main body, the partition plate is sandwiched between rib upper end faces of the case main body and an outer frame end face of the case lid so that the position of the partition plate is fixed. Ink outlet parts, of the ink bags, are overlaid on each other in a case thickness direction so that they are in contact with each other without intervention of the partition plate. Therefore, the ink cartridge is miniaturized and can be easily disassembled when it is recycled.
