A body (1, 1′, 1″) produced by an in-mold process has a first film (2, 2′, 2″) with at least one electrical or electronic functional layer (25). In a functional area (20a, 20a′, 20a″) of this functional layer, at least one electrical or electronic component is provided, and at least one electrical connection for this is provided in a contact area (20b, 20b′, 20b″). The first film is partially back-injection molded with a plastic main material (3, 3′, 3″) such that the contact area (20b, 20b′, 20b″) is at least partially free from this plastic main material (3). Suitable formation of the first film (2, 2′, 2″) guarantees that a tab (F) separated from the plastic main material (3, 3′, 3″) is provided which adjoins a back-injection molded part of the first film in an area of surface (20c, 20c′, 20c″) of the body which is at a distance from an edge (31, 31′) of the body delimiting the surface (30) with the first film.
