Abstract
A piezoelectric element that includes a plurality of laminated piezoelectric films and adhesive layers. The piezoelectric films stretch and contract in a predetermined direction parallel to principal surfaces thereof when a voltage is applied thereto. The adhesive layers are formed partially between the piezoelectric films when seen from a plan view, are aligned at intervals in the predetermined direction of the stretching and contracting of the piezoelectric films and bond the piezoelectric films to each other. The adhesive layers are formed at both ends of the piezoelectric films in the predetermined direction.
