To provide a liquid transferring apparatus equipped with a piezoelectric actuator excellent in durability and additionally with improved driving efficiency, and a method for manufacturing the liquid transferring apparatus like this.
When the length in the radial direction of a pressure room 14 is W, and the length in the radial direction of a part formed in a region overlapped to a part on one side in the radial direction of the edge part of the pressure room 14 is A, the length A in the radial direction of an individual electrode 32 is determined so as to make the amount of deformation of a vibrational plate 30 large, based on the value of A/(W/2) and a relation with the amount of the deformation of the vibrational plate 30 when a driving voltage is applied on the individual electrode 32.
