Patent ID: 8308276

Claim:
A liquid ejecting head comprising: first and second pressure generating chambers which are provided in parallel on a flow path forming substrate such that each of the first and second pressure generating chambers forms a row so as to communicate with nozzle openings for ejecting liquids; first and second piezoelectric devices each of which causes the volumes of the first and second pressure generating chambers to change, respectively, through a vibration plate formed on the flow path forming substrate; a common fixing member which is arranged between the first and second piezoelectric devices at a position opposite to the first and second pressure generating chambers, a part of each of the first and second piezoelectric devices being bonded to the common fixing member; and a signal line film which has input terminals through which a driving signal for driving the first and second piezoelectric devices is supplied from the outside and output terminals through which the driving signal is supplied to the first and second piezoelectric devices, the signal line film having flexibility, wherein the signal line film includes: a first wiring portion having the input terminals and the output terminals for supplying the driving signal to the first piezoelectric devices at one side face of the fixing member; a second wiring portion extending from the first wiring portion to the other side face of the fixing member and having the output terminals for supplying the driving signal to the second piezoelectric devices; a coupling portion coupling the first wiring portion to the second wiring portion by extending from the first wiring portion to the other side face of the fixing member; and a notch portion, which is provided at a region of the signal line film, close to the flow path forming substrate as compared to the coupling portion; and wherein the signal line film is configured such that end face of the fixing member, which is bonded to the piezoelectric devices, is exposed through the notch portion.
