摘要：
An inkjet printing cartridge capable of ejecting miniaturized ink droplets in a stable manner while avoiding the complexity of the structure and control as well as suppressing the cost rise. For this purpose, the inkjet printing cartridge is formed of a material having the permeability to liquid and gas, and the ink supply path for supplying ink to the ejection opening having a relatively small ejection amount is arranged adjacent to other ink supply paths via walls.
