ABSTRACT:
An ink-jet head having a passage unit including pressure chambers each having one end coupled to a nozzle and the other end to be coupled to an ink supply source. The pressure chambers are arranged in a matrix adjacent to each other. The ink-jet head further includes an actuator unit attached to a surface of the passage unit for changing the volume of each of the pressure chambers. The actuator unit includes a piezoelectric sheet disposed to continuously extend over the pressure chambers, a common electrode disposed on one side of the piezoelectric sheet and kept at a constant potential, individual electrodes disposed on the other side of the piezoelectric sheet at positions corresponding to the respective pressure chambers, and recesses formed in regions of the piezoelectric sheet corresponding to portions between the pressure chambers.
