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.

Abstract: A vibrating device that includes a pair of vibrators, a vibrating body that includes a conductor, a touch panel sensor that includes touch sensors, and a printed circuit board on which a drive circuit is formed. The touch panel sensor is attached to one principal surface of the vibrating body. Moreover, both ends of the vibrating body on the other principal surface of the vibrating body are fixed to the pair of vibrators. The vibrating body is a conductor that is arranged between the touch sensors and the drive circuit. The conductor is connected to a reference potential of each touch sensor and the printed circuit board is positioned between the two vibrators.
