Patent ID: 8348394

Claim:
A liquid ejecting head comprising: an actuator unit having a pressure generating element which creates pressure change in a liquid in a pressure chamber by applying a driving voltage between a discrete element electrode and a common element electrode to eject the liquid from nozzles which communicate with the pressure chamber, the actuator unit having plural pressure generating element groups in which a plurality of pressure generating elements are provided in row; a discrete element electrode terminal which is electrically conducted with a discrete element terminal of the pressure generating element and is formed between the pressure generating element groups on a pressure generating element mounting surface of a substrate with the pressure chamber formed thereon; a driving IC which is placed between the adjacent pressure generating element groups on the pressure generating element mounting surface; a printed substrate which is placed at a side opposite to the substrate side of the driving IC; and an input pad which is formed at a position corresponding to an input terminal of the driving IC on the pressure generating element mounting surface; in which an output terminal of the driving IC is electrically bonded to the discrete element electrode terminal, the input terminal of the driving IC is electrically bonded to the input pad, and the input pad is electrically bonded to a substrate terminal of the printed substrate.
