Patent ID: 8220905

Claim:
A liquid transporting apparatus comprising: a channel unit in which a liquid channel including a plurality of pressure chambers arranged along a plane is formed; a piezoelectric actuator which applies a pressure to a liquid in the pressure chambers and which includes: a vibration plate disposed on the channel unit to cover the pressure chambers; a plurality of piezoelectric elements disposed on a surface, of the vibration plate, not facing the pressure chambers; a first electrode disposed on the surface, of the vibration plate, which is in contact with the piezoelectric elements; and second electrodes disposed on surfaces, of the piezoelectric elements, opposite to surfaces in contact with the vibration plate; and a flexible wiring member physically connected to the second electrodes; wherein each of the piezoelectric elements is disposed to face one of the pressure chambers corresponding thereto and the piezoelectric elements are arranged to be isolated from each other; wherein a support section is arranged on the surface, of the vibration plate, not facing the pressure chambers, at an area different from another area facing the pressure chambers, the support section being made of a piezoelectric material same as that of the piezoelectric elements, and the support section being separate and distinct from the plurality of piezoelectric elements; and wherein a surface of the support section which does not face the vibration plate is physically joined to the flexible wiring member to physically support the flexible wiring member.
