Abstract
The piezoelectric multilayer component includes a piezo stack having an alternating sequence of piezoelectric ceramic layers and inner electrodes, and a passivation on an outer side. The passivation is produced from a piezoelectric ceramic material which is different from the material of the ceramic layers. In the production method, the passivation is polarized together with the ceramic layers.
