Abstract
There is provided a liquid discharging head including: a pressure chamber configured to apply a pressure to a liquid so as to discharge the liquid from a nozzle; a descender arranged to overlap, in a plan view, with the nozzle and communicating the pressure chamber and the nozzle with each other; at least one return throttle channel connected to the descender; and a return manifold which communicates with the at least one return throttle channel and which is configured to receive the liquid not having been discharged from the nozzle. A cross section of the descender orthogonal to a depth direction of the descender is a non-circular shape having a major axis and a minor axis. The at least one return throttle channel is connected to at least one of a first end side of the minor axis and a second end side of the minor axis.
