Claim 11:
12. A liquid discharging head comprising:
a pressure chamber substrate on which a plurality of first pressure chambers and a plurality of second pressure chambers are formed;
a first piezoelectric element line in which a plurality of piezoelectric elements is arranged, each of the plurality of piezoelectric elements being provided for each of the plurality of first pressure chambers;
a second piezoelectric element line in which a plurality of piezoelectric elements is arranged, each of the plurality of piezoelectric elements being provided for each of the plurality of second pressure chambers;
a wiring substrate that is disposed between the first piezoelectric element line and the second piezoelectric element line and supplies a voltage to the plurality of piezoelectric elements in the first piezoelectric element line and the plurality of piezoelectric elements in the second piezoelectric element line; and
a vibration plate that is disposed, in a thickness direction of the pressure chamber substrate, between the pressure chamber substrate and the plurality of piezoelectric elements, wherein
the wiring substrate includes
a main body portion that extends in the thickness direction of the pressure chamber substrate, and
a terminal that is bent toward a side of the second piezoelectric element line from an end portion of the main body portion on a side of the pressure chamber substrate,
an adhesive having a first amount exists on a side of the first piezoelectric element line, of a joint of the wiring substrate and the pressure chamber substrate or the vibration plate, and
an adhesive having a second amount exists on a side of the second piezoelectric element line of the wiring substrate, of the joint.
