Abstract
The invention relates to actuator module () having a piezoceramic multilayer actuator () arranged in a casing (). In order to avoid an increase in conductivity and hence rising leakage current at the actuator surface even after a long period of use, the invention proposes that the casing () is hermetically sealed, and a chamber () is arranged between the multilayer actuator () and the casing (), which chamber is entirely or partially filled with a medium () that chemically transforms and/or binds water.
