Abstract:
A liquid ejecting head includes nozzles that eject a liquid, communication paths in which the respective nozzles are disposed and which are arrayed and partitioned from adjacent ones of communication paths by partition walls, pressure chambers which communicate with the respective communication paths and which are arrayed and partitioned from adjacent ones of pressure chambers by partition walls, pressure generating portions that are provided in the respective pressure chambers and that vary a pressure of the pressure chambers to cause the liquid to be ejected from the nozzles, and common flow paths through which at least one of supplying and discharging the liquid is performed to and from flow paths including the communication paths and the pressure chambers. A compliance of the partition walls of the communication paths is made larger than a compliance of the partition walls of the pressure chambers.
