PROBLEM TO BE SOLVED: To provide an inkjet cartridge which realizes a high quality, a high reliability, a saved space and is inexpensive. SOLUTION: Two ink tanks are linked by a spring member via a pressure plate present at the outside of a sheet at raw ink tanks of the ink cartridge. Since negative pressures of the two ink tanks are kept by one spring member, the negative pressures of both are made the same at all times. Variation of a discharge amount is improved accordingly.
