Zusammenfassung:The invention relates, inter alia, to an additional contact (30) for a piezoelectric component (10) in the form of a multilayer structure and to a corresponding component, wherein the piezoelectric component (10) is formed by a stack (17) of alternating piezoelectric ceramic layers and electrode layers. The additional contact (30) has a contact element (31) with a contact zone (33) for connection to an electrical connecting element (20) and with a fastening zone (34) for connection to a metallized part (15, 16). In order to minimize harmful tensile/pressure loads in the additional contact (30), the additional contact (30), especially the contact element (31), is shaped so as to allow for a load distribution of the critical tensile loads, for example by means of at least one bend (32) in the contact element (31).
