1. A liquid discharging head comprising:
a plurality of individual channels;
a first common liquid chamber provided commonly for the individual channels; and
a second common liquid chamber provided commonly for the individual channels,
wherein liquid is supplied from the first common liquid chamber to the individual channels and the liquid flows into the second common liquid chamber from the individual channels,
wherein each of the individual channels has:
a pressure chamber;
a first channel:
a nozzle connected to the first channel and configured to discharge the liquid;
a second channel separated from the nozzle in a first direction and connecting the pressure chamber and the first channel, the first direction being a direction along a nozzle surface, of the liquid discharging head, in which the nozzle is opened; and
a third channel connected to the first channel on a side opposite to the second channel in the first direction with the nozzle sandwiched between the third channel and the second channel, and
wherein the first channel is bent to be convex to one side in a second direction, which is along the nozzle surface and orthogonal to the first direction, and a flowing direction of the liquid flowing through the first channel is bent to be convex to the one side in the second direction.
