ABSTRACT:
A liquid ejecting head includes a nozzle plate formed with a plurality of nozzle orifices; a flow path forming plate, formed with a plurality of pressure chambers which communicate with the nozzle orifices respectively, a reservoir which stores liquid therein, and a plurality of liquid flow paths which communicate the pressure chambers with the reservoir respectively; an elastic plate, applying pressure to the liquid in the pressure chambers; and a plurality of driver elements, each pushing the elastic plate so as to vary a volume of each corresponding pressure chamber. The flow path forming plate is comprised of (110) orientation silicon single crystal. A liquid flow path wall partitioning adjacent liquid flow paths and a pressure chamber wall partitioning adjacent pressure chambers are formed continuously. A width of the liquid flow path wall is greater than that of the pressure chamber wall.
