PROBLEM TO BE SOLVED: To provide an organic EL device capable of feeding a power to the inside of a light-emission region actually emitting light with certainty even when using a solder.SOLUTION: An organic EL device has a cross section structure including an organic EL element 10 comprising a first electrode layer 3, a function layer 5, and a second electrode layer 6 on a substrate 2 extended in a planar shape. In a plan view of the substrate 2, a light-emitting region 30 actually emitting light is provided. The organic EL device comprises: a power feeding part contributing to power feeding to the light-emitting element; and power feeding members 11, 12, and 13 electrically connectable with an external power supply; and a conductive adhesive layer 8 adhering the power feeding part and the power feeding members 11, 12, and 13 with each other. The power feeding part has a lamination structure in which at least the first electrode layer and the second electrode layer are directly contacted with each other. The conductive adhesive layer 8 has a composition consisting of: one kind of element selected from coper, silver, nickel, zinc, bismuth, indium, and aluminum; and an alloy including tin element. |
