A tris-type iridium complex in which a ligand having a distinctive nitrogen-containing five-membered heterocyclic skeleton is coordinated is provided. The ligand has a nitrogen-containing five-membered heterocyclic skeleton composed of 2 to 4 nitrogen atoms and one or more carbon atoms. In the skeleton, an aryl group is bonded to a carbon atom on both sides of which nitrogen atoms are positioned, and a tricycloalkyl group having a bridge structure and having 9 or 10 carbon atoms is bonded to one of the two nitrogen atoms positioned on both the sides of the carbon atom. The tricycloalkyl group having a bridge structure and having 9 or 10 carbon atoms may be an adamantyl group or a noradamantyl group.
