ＥＬ素子１０が形成されている。That is, as shown in FIGS. 6 and 7, the back electrode 1
A transparent sheet forming an insulating substrate on which an insulating layer 2 and a light emitting layer 3 are sequentially laminated, and on one side a transparent electrode 4 and a reinforcing electric circuit portion 5 are formed around the outer surface of the transparent electrode 4. 6 is placed on the light emitting layer 3 so that the transparent electrode 4 is in contact with the light emitting layer 3, and a pair of leads serving as terminals are attached to the back electrode 1 and the electrical circuit section 5 connected to the transparent electrode 4 using adhesive tape 7. After connecting the pieces 8 and pulling out the lead pieces 8 in the circumferential direction, the whole is covered with a transparent moisture-proof film 9 with adhesive.
A thin flat plate-like EL element 10 is formed by enclosing and laminating the EL element 10.

た。Since the back electrode 1 and the transparent electrode 4 are made of thin and weak materials,
It is not possible to directly connect a wiring cord from an external power source to these by soldering or the like, so conventionally, as described above, the wiring section 5 connected to the back electrode 1 and the transparent electrode 4 was coated with copper foil, etc. The lead piece 8, which has sufficient strength and can be connected to the wiring cord, was fixed with adhesive tape 7, but there were many parts and it was difficult to connect it. It took time and effort to apply the T-tape 7.

がずれてしまうという問題があった。Furthermore, as the area of the adhesive tape 7 increases, the area covering the light emitting layer 3 also increases, and accordingly, the EL
Since the light-emitting area of the element 10 is made small, it can be made wide.For this reason, sufficient adhesive force cannot be obtained, and even if the lead piece 8 is fixed with this adhesive tape 7, it is surrounded by the moisture-proof film 9. There was a problem in that the position of the lead piece 8 was shifted when laminating the lead piece 8.
