Abstract

Multiple contacts are provided in an electrical contacting arrangement of a sensor element, and the sensor element has a connection-side section with contact points, or contact pads, which are each integrally bonded to a corresponding contact. Each of the multiple contacts, at least on the section in contact with the contact point on the sensor element, has a layer by which the integral bond is formed between the contact and the contact point on the sensor element. The contacts are joined to the corresponding contact points on the sensor element by diffusion soldering or diffusion welding. Each contact has a curved intermediate section which compensates for thermal and/or mechanical expansion and movements.
