Ink jet head and fabrication method of the same

摘要

Nozzles (100) for jetting ink droplets and ink chambers (101) connected to the respective nozzles are formed in a substrate (1). Ink filling the ink chambers is pressurized. Ink pools (103) are also formed adjacent to the ink chambers through thin partition walls (104), for supplying ink to the ink chambers. The partition wall makes a predetermined angle with respect to a surface of the substrate. Further, the nozzles are arranged in a line and row matrix and the line of nozzles or the side of ink pools makes a constant angle with respect to a printing direction. <IMAGE>
