Abstract:
1. A liquid ejecting head comprising: a plurality of pressure generation elements each of which applies a pressure change to liquid retained in a corresponding pressure generation chamber that is in communication with a corresponding nozzle opening so as to discharge the liquid from the nozzle opening; a fixation plate to which a rear part of each of the plurality of pressure generation elements is fixed, the rear part being opposite to a front part, the front part being closer to the corresponding pressure generation chamber; a plurality of nozzle lines each of which includes a plurality of nozzle openings arrayed in a line, the plurality of nozzle lines including at least two nozzle lines provided in parallel to and next to each other; and a flexible substrate through which an electric signal sent from the outside is supplied to the pressure generation chambers, wherein pressure generation elements provided for respective pressure generation chambers that are in communication with respective nozzle openings that belong to one of the two nozzle lines and pressure generation elements provided for respective pressure generation chambers that are in communication with respective nozzle openings that belong to the other of the two nozzle lines are fixed to the fixation plate, which is a common plate, with the fixation plate being sandwiched between the pressure generation elements for the one nozzle line and the pressure generation elements for the other nozzle line, a wiring portion is formed at one end part of the fixation plate opposite to the other end that is closer to the pressure generation chambers, and the flexible substrate is connected to the wiring portion.
