The present invention is to provide an organic electroluminescent lighting device that can improve brightness uniformity. The organic electroluminescent lighting device includes: organic light-emitting film 5; a pair of electrode films 2a and 2b that are stacked to face each other sandwiching organic light-emitting element 5, wherein electrode films 2a and 2b are formed rectangular and different from each other in polarity; wherein electrode films 2a comprises power supply terminal sections 6a and 6b which are each of edge sides which face each other at a surface of one electrode film 2a; and auxiliary electrode film group 3 including at least one of a plurality of first auxiliary electrode films 3a and a plurality of second auxiliary electrode films 3b which are located away from each other on the surface of electrode film 2a. A sectional area viewed at a section where the plurality of first auxiliary electrode films 3a is cut in a direction perpendicular to the edge sides becomes larger in relation to increasing distance from the edge sides. A sectional area viewed at a section where the plurality of second auxiliary electrode films 3b is cut in a direction parallel to the edge sides becomes larger in relation to increasing distance from the edge sides. |
