Claim 0:
1. A liquid discharging head having a plurality of plates stacked in a stacking direction, the liquid discharging head comprising:
a plurality of individual channels each has a nozzle configured to discharge a liquid;
a supply manifold which is provided commonly to the plurality of individual channels and which is configured to supply the liquid to the plurality of individual channels;
a plurality of supply throttles each connecting one of the plurality of individual channels and the supply manifold;
a return manifold which is provided commonly to the plurality of individual channels and into which the liquid flowed out from the plurality of individual channels flows; and
a plurality of return throttles each connecting one of the plurality of individual channels and the return manifold, wherein
each of the plurality of individual channels, the supply manifold, the plurality of supply throttles, the return manifold and the plurality of return throttles is formed in the plurality of plates;
the plurality of supply throttles is formed in a first plate of the plurality of plates and the plurality of return throttles is formed in a second plate of the plurality of plates different from the first plate;
each of the plurality of supply throttles has a cross section, in a plane orthogonal to a flowing direction of the liquid in the each of the plurality of supply throttles, which is a rectangle having a first side and a second side, a length of the second side being not less than a length of the first side;
each of the plurality of return throttles has a cross section, in a plane orthogonal to a flowing direction of the liquid in the each of the plurality of return throttles, which is a rectangle having a first side and a second side, a length of the second side being not less than a length of the first side;
the length of the first side of each of the plurality of supply throttles and the length of the first side of each of the plurality of return throttles are substantially identical to each other;
the length of the second side of each of the plurality of supply throttles and the length of the second side of each of the plurality of return throttles are substantially identical to each other; and
an aspect ratio of each of the plurality of supply throttles which is a ratio between the first side of each of the plurality of supply throttles and the second side of each of the plurality of supply throttles and an aspect ratio of each of the plurality of return throttles which is a ratio between the first side of each of the plurality of return throttles and the second side of each of the plurality of return throttles are substantially identical to each other.
