A fuel injection valve for a fuel injection system of an internal combustion engines includes a valve closing body cooperating with a valve seat body to form a sealing seat, and a piezoelectric actuator for actuating the valve closing body. The piezoelectric actuator includes piezo layers and one or more temperature compensation layers. The temperature compensation layers have a temperature expansion coefficient having an operational sign opposite the sign of the temperature expansion coefficient of the piezo layers.
