Organic electroluminescent lighting device and method for manufacturing same

An organic electroluminescent lighting device, comprising:

• a base substrate;
• an organic electroluminescent element formed on a surface of the base substrate, the organic electroluminescent element comprising an optically-transparent first electrode, a light-emitting layer, and a second electrode facing the first electrode with the light-emitting layer interposed therebetween;
• and
• an opposed substrate, the organic electroluminescent element formed on the surface of the base substrate being sealed with the opposed substrate which has a concave portion in a center thereof and which is placed opposite to the base substrate, wherein
• the organic electroluminescent lighting device further includes an auxiliary electrode which is formed on the surface of the base substrate so that the auxiliary electrode is across an opening edge of the opposed substrate, the auxiliary electrode comprising a transparent conductive layer made of optically-transparent electrode material, a conductive resin layer made of electric conductive resin, and a metal film layer made of metal having higher electric conductivity than that of the material of the transparent conductive layer, which are stacked in this order on the surface of the base substrate, and
• the auxiliary electrode is formed with a block structure configured to block moisture permeation through the conductive resin layer into the organic electroluminescent element from outside.
