Abstract:
1. An ink ejecting head comprising: a nozzle sheet having nozzles for ejecting droplets; a head chip having an energy generator opposing each of the nozzles; a chamber-forming member interposed between the nozzle sheet and the head chip for defining the space for a liquid chamber between the energy generator and the nozzle; an electrode provided in a surface of the head chip, the surface opposing the nozzle sheet, and provided in at least a part of an area where no chamber-forming member is disposed; a wiring layer having a first terminal and disposed on a surface of the nozzle sheet, the surface adjacent to the head chip; and a bonding layer disposed on the first terminal of the wiring layer and being at least in contact with the electrode of the head chip; wherein the energy generator applies energy to liquid in the liquid chamber for ejecting the liquid from the nozzle; and wherein the bonding layer and the electrode of the head chip are bonded by ultrasonic bonding.
