摘要

An elongated EL element and a manufacturing method thereof. An elongated substrate (12) has a back electrode (12a), an insulating layer (12b) and a luminescent layer (12c) which are superimposed upon each other. A transparent conductive film (14) is superimposed upon the substrate. An auxiliary electrode (17) narrower in width than that of each of the substrate and the transparent conductive film has an insulating film (20), a conductive metal layer (21) and a conductive adhesive layer (22) which are superimposed upon each other. The auxiliary electrode is sandwiched between the substrate and the transparent conductive film superimposed one upon the other, and extends longitudinally of the substrate and the transparent conductive film, wherein the insulating film is in contact with the luminescent layer of the substrate, while the conductive adhesive layer is bonded to the transparent conductive film. An assembly of the substrate, the transparent conductive film and the auxiliary electrode is covered sealingly with dampproof film material (18).
