A piezoelectric component ( 1 ) has at least one monolithic piezo element ( 10 ) having an electrode layer ( 101 ), at least one further electrode layer ( 102 ), at least one piezoceramic layer ( 103 ) disposed between the electrode layers and at least one predetermined breaking point ( 100 ) which, in the event of mechanical overload of the piezo element, leads to the formation of a specific crack ( 110 ) in the monolithic piezo element, wherein the predetermined breaking point includes the electrode layer. The component is, for example, a piezoelectric actuator with a monolithic actuator body ( 2 ) in which piezo elements with predetermined breaking points and further piezo elements ( 11 ) without predetermined breaking points are arranged one on top of the other and sintered collectively.
