Abstract:
An ink-jet head includes a nozzle plate having nozzles, a vibrating plate on the nozzle plate, liquid chambers formed of spaces partitioned by division walls, a piezoelectric element having a common electrode, a piezoelectric body and an individual electrode layered in this order on a surface of the vibrating plate, a first insulator film having a first opening and a second insulator film having a second opening layered in this order on the first surface, a first wire drawn from the individual electrode via the first opening and the second opening, a third insulator film having a third opening on the first wire; and a second wire drawn via the third opening, where the third insulator film is formed in a first region of the second insulator film and is not formed in a second region excluding a region including the first wire formed above the liquid chamber.
