Structure of lead conductor for third electrode of three-electrode type electroluminescent lamp
 A three-electrode type electroluminescent lamp has a transparent electrode connected to a rear side lead conductor, and an electroluminescent body sandwiched between the transplant electrode and the backing electrode. A third plate-like electrode is laid over the backing electrode in an electrical insulation relation with the backing electrode, and a third lead conductor is formed of an integral extension of the third electrode. The integral extension of the third electrode extends outwardly from an edge of the third electrode near to the edge region of the transparent electrode connected to the base end portion of the first lead conductor, so as to avoid the edge region of the transparent electrode on which the base end portion of the first lead conductor is laid and also to extend along the first lead conductor excluding the base end portion. A printed-wiring board having a plurality of printed wirings is mounted on the electroluminescent lamp. The third lead conductor is electrically connected at its tip end to a corresponding one of the printed wirings by a mechanical solderless connection using a clamping member.
