<p>The invention relates to a piezo-element comprising a multilayer structure of piezo-layers (2; 20) with electrodes (6, 7; 21, 22) arranged therebetween. The inventive piezo-element is provided with a mutual lateral contacting of said electrodes (6, 7; 21, 22) that is effected by outer electrodes (9, 10). The individual piezo-layers (4) are comprised of a continuous film (2; 20) which can be folded during production and which is partially or completely provided with the electrically conductive electrodes (6, 7; 21, 22). The piezo-layers (2, 20) are formed by folding said film at notches (5, 5.1, 5.2) placed at predetermined intervals in a manner that is transversal to the direction of folding, whereby the inner electrodes (6, 7; 21, 22) are formed by the metallized layers located on the inner side of the notches (5, 5.1, 5.2) after folding.</p> |
