Abstract:
Provided is a liquid discharging head including: a nozzle discharging a liquid; a chamber plate having a plurality of pressure chambers, a drive element provided to correspond to each of the pressure chambers, and a plurality of lead electrodes for supplying an electric signal to the drive element; and a circuit substrate having a terminal coupled to the lead electrode. A first pressure chamber and a second pressure chamber communicate with the nozzle in common. The chamber plate includes a first individual lead electrode for the drive element corresponding to the first pressure chamber and a second individual lead electrode for the drive element corresponding to the second pressure chamber. The terminal of the circuit substrate is coupled so as to overlap the first individual lead electrode and the second individual lead electrode in plan view.
