ABSTRACT:
A liquid transporting apparatus includes a channel unit in which liquid transporting channel transporting the liquid is formed, the liquid transporting channel including a pressure chamber; a piezoelectric actuator which is connected to the channel unit, and which applies a pressure to the liquid in the pressure chamber, the piezoelectric actuator having: a piezoelectric layer; a first electrode arranged on a first surface of the piezoelectric layer to face the pressure chamber; a second electrode which is arranged, to face the first electrode, on a second surface of the piezoelectric layer different from the first surface; third electrodes arranged on the piezoelectric layer to sandwich the first electrode in a plan view; and fourth electrodes which are arranged, to face the third electrode, on the piezoelectric layer; a voltage applying mechanism which applies a voltage to the piezoelectric actuator; and a controller which controls the voltage applying mechanism.
