Abstract
A lead electrode unit for an EL element includes a lead electrode structure for a transparent electrode layer and a lead electrode structure for a back electrode layer. The EL element has a light-emitting layer, an insulating layer and the back electrode layer formed in that order on a transparent electrode layer on the transparent substrate. The uppermost face of the EL sheet structure is coated with a protective layer. A lead electrode runs from the transparent electrode layer. A lead electrode layer runs from the back electrode layer. An electrode plate is bonded to the lead electrode via an electroconductive adhesive. A connector is fitted to the electrode plate. The connector is bent to form its legs, and the legs run through the electrode plate. The end of each leg is folded to thereby fix the connector.
