An ink-jet head includes a channel unit having pressure chambers; and a piezoelectric actuator which includes a vibration plate having an electroconductive substrate and an insulating layer, a piezoelectric layer arranged in an area overlapping with the pressure chamber, and a common electrode and an individual electrode formed on the piezoelectric layer. A recess is formed in an area overlapping with the pressure chamber. A wiring connected to the individual electrode is formed on the upper surface of the vibration plate in an area in which the piezoelectric layer is not formed. Accordingly, there is provided a liquid-droplet jetting apparatus and a liquid transporting apparatus having an improved durability, requiring a less electric power consumption, capable of performing a pulling ejection, and in which a wiring can be performed highly densely.
