Provided is an organic EL light emitting element that prevents variations in brightness caused by resistance in a transparent electrode layer without a separate auxiliary electrode being provided. This organic EL light emitting element has a transparent conductive layer, organic light emitting unit layer, and metal layer in that order on a transparent substrate. The metal layer is divided into negative electrode regions and auxiliary electrode regions that are electrically separated by a metal layer dividing channel. In the auxiliary electrode regions, the metal layer and transparent electrode layer are electrically connected via first type connecting channels, which are opening parts in the organic light emitting unit layer. The dividing channels and connecting channels are preferably formed by laser beam irradiation.
