The present invention relates to a piezo actuator (10) in multilayer design, in which piezoelectric layers (14) and electrode layers (12) are arranged alternately one above the other to form a stack (16). Several of the electrode layers (12) are electrically conductively connected to a contact pin (24), with a lead-through (30) being arranged electrically conductively on the contact pin (24). The lead-through (30) has a contact point (32) with the contact pin (24) and a free end (34) for establishing an electrical connection of the piezo actuator (10). A straight line running through the contact point (32) and the free end (34) of the lead-through (30) encloses an angle (p) with a longitudinal axis (18) of the contact pin (24) which is greater than 0° and less than 180°.
