Abstract:
A piezoelectric component comprises a parallelepipedal basic body made of piezoelectric material which has an input region and an output region at opposite longitudinal ends of the basic body. Furthermore, the piezoelectric component comprises first and second primary electrodes which are arranged inside the input region and first and second secondary electrodes which are arranged inside the output region. The primary electrodes are at a greater interval from longitudinal lateral faces of the basic body in a subregion which faces the output region than in the subregion which is remote from the output region. Likewise, the secondary electrodes are at a greater interval from the longitudinal lateral faces of the basic body in a subregion which faces the input region than in a subregion which is remote from the input region.
