A piezoelectric loudspeaker includes a diaphragm and a piezoelectric element bonded on a principal surface of the diaphragm. An electrode layer is provided on the surface of the piezoelectric element. The piezoelectric element has a structure formed by alternately laminating at least three piezoelectric layers and electrode layers in order to achieve a sufficient driving force. A conductive path composed of a strip-shaped metal foil and having an adhesive layer on the reverse face thereof is provided on the surface of the electrode layer. The adhesive layer may be conductive or nonconductive. Conductive paste having a low rigidity and a low volume resistivity is applied so as to be disposed over the surfaces of the conductive path and the electrode layer. Thus, a conductive layer having a Young's modulus of 100 MPa or less and a volume resistivity of 6×10−3 Ωcm or less is provided.
