摘要： An ink-jet head comprises a passage unit including pressure chambers each having one end connected with a nozzle and the other end to be connected with an ink supply source. The pressure chambers are arranged along a plane to neighbor each other. The ink-jet head further comprises actuator units fixed to a surface of the passage unit for changing the volume of each pressure chamber. Each actuator unit includes pressure generation portions respectively corresponding to pressure chambers, and is formed to extend over the pressure chambers. The actuator units are arranged along the longitudinal direction of the passage unit so that each neighboring actuator units partially overlap each other in the lateral direction of the passage unit. Each actuator unit has a basic region where many pressure generation portions are formed in a matrix, and an additional region neighboring the basic region in the lateral direction of the passage unit. In the additional region, pressure generation portions are formed to correspond to a gap portion between the pressure generation portions in the basic region of the actuator unit and the pressure generation portions in the basic region of another actuator unit neighboring that actuator unit.

摘要： There is provided a piezoelectric actuator configured to displace to project toward a pressure chamber so as to apply pressure to a liquid inside the pressure chamber, the piezoelectric actuator including: a vibration plate having a compressive stress; a piezoelectric layer having a pulling stress; and an individual electrode. The compressive stress of the vibration plate has a magnitude which is not less than a threshold value at which an extreme point is generated in a relationship between a compliance of the piezoelectric actuator and a displacement volume of the pressure chamber in a case that an electric voltage is applied to the piezoelectric actuator, the displacement volume converting from increasing to decreasing relative to increase in the compliance at the extreme point; and the thickness of the piezoelectric actuator is not less than a first thickness corresponding to a compliance allowing the extreme point to generate.
