PURPOSE:To provide a layer-built displacement element having high bond strength and reliability as well as high dimensional accuracy and productivity by providing clamping members adapted to exert clamping force in the layer stacking direction so that a plurality of sheets and internal electrodes interposed therebetween are integrally clamped by these clamping members. CONSTITUTION:A plurality of sheets 1 of an electromechanical converting material are stacked with an internal electrode 3 interposed therebetween, the internal electrode having horizontal outline configurations substantially identical with those of the sheets 1. A pair of external electrodes 8a, 8b are provided on the sides of the layer-built body so that they are connected with alternate layers of the internal electrodes 3. In the layer-built displacement element thus constructed, clamping members 4, 5 adapted to exert the clamping force in the stacking direction are provided so that said plurality of sheets 1 and the internal electrodes 3 of the conductive metallic material interposed between the sheets 1 are clamped integrally. For example, said sheets 1 and said internal electrodes 3 may be provided with a through hole 2, so that a bolt 4 is inserted through the through hole 2 and tightened by a nut 5. |
