A laminated displacement transducer element formed by alternately laminating a plurality of thin sheets made of an electro-mechanical transducer material 1, 2 and a plurality of internal electrodes made of an electrical conductive material 3, 4. External terminals made of an electrical conductive material are connected to the side edges of alternate internal electrodes, and the side edges of the alternate internal electrodes protrude from the side edges of the thin sheets. The protruded portions are formed into an enlargement 5a, e.g. in cross-sectional a torpedo or mushroom shape, having a thickness larger than the thickness of the internal electrodes. Insulating layers 7 are provided on and in the vicinity of the side edges of other internal electrodes between the protruded portions. Finally external electrodes 9 are provided around the protruded portions and outside the insulating layers. <IMAGE> |
