Abstract:
A liquid discharging head includes a stacked body in which plates are adhered to each other by an adhesive. The stacked body is provided with: individual channels including nozzles and pressure chambers, respectively, and aligned in a predetermined aligning direction, the pressure chambers being configured to be pressurized to discharge liquid from the nozzles; a supply manifold being communicated with the individual channels and supplying the liquid to the individual channels; a return manifold being communicating with the individual channels and configured to allow the liquid, which flows in the individual channels and which is not discharged from the nozzles, to flow therethrough; and a dummy channel arranged side by side with the individual channels in the aligning direction. The dummy channel is positioned at outside with respect to an outermost individual channel in the aligning direction.
