The laminated piezoelectric element comprises a plurality of layers including first electrodes, piezoelectric material bodies, and second electrodes, wherein: the layers are laminated in order of the first electrode, the piezoelectric material body, the second electrode, and the piezoelectric material body; a plurality of active parts of the laminated piezoelectric element, where the piezoelectric material bodies are capable of actively expanding and contracting when a voltage is applied to the first electrode and the second electrode that are mutually opposing across the piezoelectric material body, are two-dimensionally arranged in a row direction and a column direction; and the first electrodes are common to the plurality of active parts in the row direction and the second electrodes are common to the plurality of active parts in the column direction.
