Patent ID: 7739777

Claim:
A method of manufacturing a liquid transporting apparatus including a channel unit in which a plurality of pressure chambers communicating with a discharge port which discharges a liquid are arranged along a flat surface; and a piezoelectric actuator which includes a vibration plate which is joined to one surface of the channel unit to cover the pressure chambers, and a piezoelectric layer formed of a piezoelectric material, and which changes selectively a volume of the pressure chambers, the method comprising: a step of providing, on the channel unit, a plate to be a vibration plate, the plate having grooves formed on a surface thereof, the grooves being associated with the respective pressure chambers; and a piezoelectric layer forming step of forming the piezoelectric layer by depositing particles of a piezoelectric material on the surface of the vibration plate on which the grooves have been formed, the particles of the piezoelectric material being deposited on a surface of the grooves such that the particles of the piezoelectric material are in contact with the surface of the grooves, wherein the piezoelectric layer on surfaces of the grooves is formed to be thinner than the piezoelectric layer in an area other than the surfaces of the grooves.
