A piezoelectric actuator of a multilayer design includes outer electrodes that are fastened by means of a bonding layer applied by thermal spraying. For example, the outer electrodes are formed as a woven wire fabric. Furthermore, a method for fastening an outer electrode in a piezoelectric actuator is specified.
