Document Type and Number:
Japanese Patent JP2003502872
Kind Code:
A
Abstract:
A piezoelectric element with a multi-layer construction of piezoelectric layers (2) that have electrodes (6, 7) disposed between them is proposed, which is provided with a contacting of the electrodes (6, 7) on alternating sides by means of external electrodes (8, 9). The individual piezoelectric layers (2) are comprised of a continuous foil made of ceramic, which can be folded during manufacture, and are completely or partially provided with the electrically conductive electrodes (6, 7); the external electrodes (8, 9) are attached to the metallized layer on the respective outsides in the bending region of the folded foil in order to produce the contact on alternating sides.
