1. A liquid discharging head comprising:
a plurality of manifolds to which liquid is supplied;
at least one nozzle row associated with each of the manifolds; and
a communicating channel directly connected to two manifolds which are included in the manifolds and which are adjacent to each other,
wherein the at least one nozzle row includes a plurality of nozzles opening in a nozzle surface and configured to discharge the liquid, the nozzles communicating with one manifold with which the at least one nozzle row is associated,
a first number is a number of the nozzle row associated with one of the two manifolds and a second number is a number of the nozzle row associated with the other of the two manifolds,
a cross-sectional area of the communicating channel is different between a case that a first number and a second number are same, and another case that the first number and the second number are different, and
the communicating channel does not overlap with the nozzles as viewed in a direction orthogonal to the nozzle surface.
