Provided is a highly-reliable organic electroluminescence element in which loss of light due to surface plasmons generated on a metal surface is suppressed, the efficiency of light extraction to outside the element, and short circuits are unlikely to occur. The organic electroluminescence element includes a metal layer (1), on a surface of which a nanosize uneven structure is provided by a nanoparticle arrangement structure (6) in which nanoparticles (6a) are arranged in a planar fashion, and an organic layer (3) disposed on the uneven surface of the metal layer (1) and constituted by a plurality of layers including a light-emitting layer (31). Each interface between the plurality of layers of the organic layer (3) is flatter than the uneven surface of the metal layer (1). |
