Abstract
A piezoelectric actuator, in particular for injectors in internal combustion engines, is provided which includes a piezoelectric module including a ceramic body and two end pieces which clamp the ceramic body axially in place, and an electrical connecting element which is secured on the piezoelectric module and which includes two contact plates leading to the ceramic body. To increase the robustness of the connecting element and to avoid fractures in the contact plates under high vibrational stresses, the contact plates are designed as one-piece metal stampings including at least partially embossed stamped edges.
