External electrode for a piezoelectric actuator

An outer electrode (17) for a multilayer component (2) comprises a first conductive layer (22) and a second conductive layer (23). The first conductive layer (22) has a connection region (20) in which a lead (18) is bonded to the first conductive layer (22) by welding in a materially closed manner. Furthermore, a solder excess (21) is provided at the connection region (20). Furthermore, a piezoceramics multilayer component (2) with such an outer electrode (17) as well as a fuel injection valve (1) with a piezoceramics multilayer component (2) configured as a piezoelectric actuator (2) are specified.
