る。[Problems to be Solved by the Invention] However, if the integrated layer 23 is formed of conductive paint in this way, the conductivity is two to three orders of magnitude lower than that of metal materials, so in order to increase the size, the integrated layer 23 is made of conductive paint. 23 needs to be made wider or thicker, which causes problems such as a reduction in the effective area and an increase in the number of steps. Furthermore, since screen printing or the like is used, the size is limited by the size of the printing machine.

In this case, it serves to prevent leakage due to contact between the metal film 3A and the A1 film 2A of the light emitting base film 2. Further, the bus bar is made of metal film (for example, without forming the adhesive layer 3B shown in FIG. 3).
It is also possible to provide only Cu, phosphor bronze, A1).
