1. A liquid discharging head comprising:
a nozzle plate having a plurality of nozzles from which liquid is discharged;
a channel member including a plurality of individual liquid chambers that are communicably connected to the plurality of nozzles, respectively; and
a common liquid chamber member for forming a common liquid chamber that supplies liquid to the plurality of individual liquid chambers and for forming a circulation common liquid chamber, wherein
the common liquid chamber and the circulation common liquid chamber are both arranged on the same side with respect to the nozzles, in a direction orthogonal to both a direction in which liquid is discharged from the nozzles and a direction in which the nozzles are aligned.
