A liquid delivering apparatus including a piezoelectric sheet which is opposed to liquid chambers and is polarized in a direction of thickness thereof; a restrictor sheet which is opposed to the liquid chambers, restricts a deformation of the piezoelectric sheet, and functions as a first electrode; and second electrodes which are opposed, via active portions of the piezoelectric sheet, to restrictive portions of the restrictor sheet, respectively, and are opposed to the liquid chambers, respectively. When an arbitrary one of the active portions of the piezoelectric sheet is deformed by an electric field which is generated in a direction substantially parallel to the direction of polarization of the piezoelectric sheet, the arbitrary one of the active portions of the piezoelectric sheet and a corresponding one of the restrictive portions of the restrictor sheet are curved in a direction to increase a volume of a corresponding one of the liquid chambers.
