Abstract
The present invention is to provide an organic electroluminescent lighting device that can reduce the occurrence of short-circuiting caused by inrush current. The organic electroluminescent lighting device includes: transparent substrate; positive electrode filmthat is formed on the surface of transparent substrateand includes terminalformed at one end or both ends and electrodeformed continuously from terminal; negative electrode terminal filmthat is formed separate from positive electrode filmon the surface of transparent substrateand includes first resistive region; organic light emitting filmformed on the surface of electrodeof positive electrode film; and negative electrode filmcontinuously formed from the surface of organic light emitting filmto the surface of negative electrode terminal film. When viewed from a first cut surface that is along a thickness direction of negative electrode terminal film, a conductor's cross-sectional area in first resistive regionis smaller than a negative electrode terminal film's cross-sectional area at boundarywith outer peripheral part of negative electrode film
