Abstract: To provide a novel organometallic complex. The organometallic complex is represented by General Formula (G1) and includes a central metal, a first ligand, and a second ligand. The first ligand and the second ligand are cyclometalated ligands. At least one of the first ligand and the second ligand includes a substituted or unsubstituted aryl group as a substituent. In General Formula (G1), each of R1 to R15 independently represents any of hydrogen, a halogen group, a substituted or unsubstituted alkyl group having 1 to 6 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. Note that at least one of R1 to R15 represents a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.
