Abstract
A piezoelectric component in the form an actuator having a monolithic multi-layer stack is disclosed. The stack comprises a large active cross sectional area and simultaneously exhibits high arc-over resistance between neighboring electrodes of different polarity. For manufacture, only the surface of the stack via which an electrical contacting of the electrode layers ensues is ground after the sintering of a stack composed of piezo ceramic layers and electrode layers arranged on top of one another.
