Abstract

One aspect relates to an electrical contacting device for a medical implantable device, including an electrically insulating base body with a first and a second surface. The base body includes a ceramics, an electrically conductive conducting element that extends from the first surface of the base body through the base body. The conducting element includes a cermet and is connected to the ceramics of the base body in firmly bonded manner through a sintered connection, a contact element including a metal. The contact element is connected to the conducting element in electrically conductive manner and can be connected to an electrically conductive structure. The contacting device includes an adhesion element. The adhesion element is connected to the contact element in firmly bonded manner and wherein the adhesion element includes an adhesion promoter in order to form a firmly bonded connection at least to the first surface of the base body.
