Patent ID: 7527361

Claim:
A liquid transporting apparatus which transports a liquid, comprising: a channel unit in which a pressure chamber, a liquid discharging port, and a liquid channel reaching up to the liquid discharging port via the pressure chamber are formed; a piezoelectric actuator which applies a discharge energy to the liquid in the pressure chamber and which includes: a plate fixed to one surface of the channel unit to cover the pressure chamber, a piezoelectric layer stacked on the plate to face the pressure chamber, and an electrode having a first area facing the pressure chamber and a second area not facing the pressure chamber, the electrode being formed on a surface of the piezoelectric layer on a side opposite to the plate so as to extend from the first area to the second area; a wiring section which is connected to the piezoelectric actuator to supply a drive voltage to the piezoelectric actuator, and which includes: a substrate which is insulative and which is arranged to cover the piezoelectric actuator; a first wiring formed on a surface of the substrate on a side opposite to the piezoelectric actuator; a first through hole formed in an area of the substrate which overlaps with the second area of the electrode; and a second through hole formed in another area of the substrate which does not overlap with the pressure chamber and is different from the second area; an electroconductive material filled in the first through hole and joined to the first wiring and the second area of the electrode to electrically connect the first wiring and the electrode; and a fixing material which is filled in the second through hole and joined to the substrate and the piezoelectric actuator to fix the wiring section to the piezoelectric actuator.
