Patent ID: 8465128

Claim:
A liquid discharge apparatus which discharges a liquid, comprising: a liquid discharge head including: a channel unit formed with a plurality of nozzles through which the liquid is discharged and a plurality of liquid channels which communicate with the nozzles respectively; a plurality of drive portions having a plurality of electrodes corresponding to the nozzles respectively and a deforming portion which is deformed to apply a jetting pressure to the liquid stored in the liquid channels according to a driving pulse applied to the electrodes; a plurality of lead portions which correspond to the electrodes, which are connected electrically to the electrodes and which are arranged to cover the electrodes while maintaining a space between the electrodes and the lead portions; and a plurality of input terminals each of which is formed integrally on a surface, of one of the lead portions, not facing the electrodes and which are electrically connected to the electrodes via the lead portions; and a circuit board via which the driving pulse is applied to the liquid discharge head, and which has a plurality of connecting terminals electrically connected to the input terminals, respectively; wherein each of the electrodes is arranged on a facing surface, of one of the driving portions, facing the circuit board, and wherein the lead portions have a bridge-shape, and each of the lead portions is bridged between two areas in an edge portion of one of the electrodes.
