ABSTRACT:
An ink jet print head, which sprays ink continuously by fixing an ink spray unit on which thin film layers each having a different residual stress are deposited so that both ends thereof are fixed on an ink chamber barrier layer located at the lower part of a nozzle plate, applying an electrostatic force to the thin film layers and then applying an impact force generated by the extension of the absolute lengths of the thin film layers caused by the difference of the residual stresses of the thin film layers.
