Abstract:
An object of the present invention is to provide a laminated piezoelectric element in which piezoelectric films are laminated, capable of easily performing connection of an electrode layer of each piezoelectric film and an external device. The piezoelectric film includes a piezoelectric layer and a laminated sheet in which an electrode layer and a protective layer are laminated, piezoelectric layers are arranged between the laminated sheets facing the electrode layer, the laminated sheet includes a protruding portion protruding from the piezoelectric layer, the protruding portion is provided with a lead-out wire attached to a surface between the electrode layer and the protective layer, and the object is achieved by contacting the lead-out wire and connecting electrode layers having a same polarity of each piezoelectric film.
