PROBLEM TO BE SOLVED: To provide a light-transmissive organic electroluminescent element, a luminaire and a method for manufacturing an organic electroluminescent element.SOLUTION: According to an embodiment, there is provided an organic electroluminescent element that includes a first electrode, a plurality of second electrodes and an organic light-emitting layer. The first electrode has a first principal surface. The first electrode has light-transmitting property. The plurality of second electrodes are opposite to the first electrode, extend along a first direction parallel to the first principal surface, and are spaced apart from each other in a second direction parallel to the first principal surface and perpendicular to the first direction. The light transmittance of the second electrodes is lower than the light transmittance of the first electrode. Side surfaces of the second electrodes are fluctuated in a wave shape along the first direction. The organic light-emitting layer is disposed between the first electrode and the second electrodes.
