A rolling bearing with an electrical circuit is disclosed. The rolling bearing includes a first electrically insulating layer, at least one second electrically insulating layer deposited directly on at least one surface section of the rolling bearing, a first electrically conductive layer provided over the first electrically insulating layer, conductor paths with contact positions adapted for electrical contacting of electrical components, and at least one second electrically conductive layer. The at least one second electrically conductive layer is structured and supported on the at least one second electrically insulating layer. The first electrically insulating layer and the first electrically conductive layer with the conductor paths and the contact positions are deposited on the at least one second electrically conductive layer.
