The present invention provides an organic electroluminescence device using a novel phosphorescent metal complex compound and having high efficiency, high luminance, and high durability. The organic electroluminescence device includes a pair of electrodes including an anode and a cathode, and one or more organic layers each containing an organic compound, the one or more organic layers being interposed between the pair of electrodes, wherein at least one of the one or more organic layers contain a phosphorescent metal complex compound having at least one ligand structure represented by the following general formula (1): where at least one of X, Y and Z represents an aromatic oligomer having 13 or more carbon atoms and bonded directly or via a linking group.
