Summary:To prevent damage to a glass substrate used in an organic EL device.SOLUTION: An organic EL element 1 includes a glass substrate 3, a transparent first electrode layer 4 provided on the glass substrate 3, an organic layer 5 provided on the first electrode layer 4, a second electrode layer 6 provided on the organic layer 5, a sealing layer 7 that seals the first electrode layer 4, the organic layer 5, and the second electrode layer 6, and a metal foil 2 provided on the sealing layer 7. The metal foil 2 has a larger area than the glass substrate 3. An end surface 2c of the metal foil 2 protrudes outward from an end surface 3c of the glass substrate 3.SELECTED DRAWING: Figure 1 【課題】有機ＥＬ素子に使用されるガラス基板の損傷を防止する。【解決手段】有機ＥＬ素子１は、ガラス基板３と、ガラス基板３上に設けられた透明な第一電極層４と、第一電極層４上に設けられた有機層５と、有機層５上に設けられた第二電極層６と、第一電極層４、有機層５、及び、第二電極層６を封止する封止層７と、封止層７上に設けられた金属箔２と、を備える。金属箔２は、ガラス基板３よりも大きな面積を有する。金属箔２の端面２ｃは、ガラス基板３の端面３ｃよりも外方に突出している。【選択図】図１
