PROBLEM TO BE SOLVED: To provide an EL sheet capable of improving electric reliability in an extraction electrode and enduring high temperature environment and strong external force. SOLUTION: An extraction electrode part 2 protrudes from an EL light emission part 1 and is provided with an extraction electrode part 21 for a transparent electrode layer and an extraction electrode part 22 for a back electrode layer. The EL light emission part 1 is constituted by laminating a light emission layer 4, an insulation layer 5, and the back electrode layer 6 sequentially on the transparent electrode layer on a transparent substrate 3. An auxiliary electrode 3a is formed in an outer peripheral part of the transparent electrode layer. Its uppermost layer is covered with a protection layer 7. An extraction electrode 21a for the transparent electrode layer is extracted from the auxiliary electrode 3a in the extraction electrode part 21. An extraction electrode for the back electrode layer is extracted from the rear surface electrode layer 6. An electrode plate 21b is bonded on the extraction electrode through electricity conducting adhesive 9. A connector 23 is brought into contact with the electrode plate 21b opposingly and is heat-pressed using solder 10. A leg part 23a formed by bending it from the connector 23 passes through the electrode plate 21b, and its tip part 23b is bent to fix the connector 23. COPYRIGHT: (C)2003,JPO
