Abstract: To provide a novel organometallic complex having high color purity. The organometallic complex is represented by General Formula (G1), and includes iridium and a ligand. The ligand includes a five-membered aromatic heterocycle including two or more nitrogen atoms and a plurality of aryl groups bonded to the five-membered aromatic heterocycle. At least one of the plurality of aryl groups includes a pentafluorosulfanyl group as a substituent. In General Formula (G1), one of P1 and P2 represents nitrogen and the other represents carbon, or both of P1 and P2 represent carbon; Q1 represents any of hydrogen, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 5 to 8 carbon atoms, a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, and a substituted or unsubstituted heteroaryl group having 3 to 12 carbon atoms; Q2 represents any of hydrogen and a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms; each of Ar1 and Ar2 independently represents a substituted or unsubstituted aryl group having 6 to 13 carbon atoms; and any one of Q1, Ar1, and Ar2 includes a pentafluorosulfanyl group.
