<p>The arrangement (1) has a piezo-actuator (2) with piezo-units clamped between an actuator head (4) and an actuator base (3). An insulation layer (11) is surrounded with the piezo-units and is made of plastic. A layer of metal foil (12) is applied on the insulation layer and in edge regions of the actuator head and the actuator base. The metal foil layer has a low thermal expansion coefficient.</p> |
