An organometallic complex emitting light with high color purity. The organometallic complex is represented by General Formula (G1). In General Formula (G1), L represents a monoanionic ligand; R
1
represents a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms or a substituted or unsubstituted aryl group having 6 to 13 carbon atoms; each of R
2
to R
5
independently represents hydrogen, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, or a substituted or unsubstituted phenyl group; the organometallic complex is monosubstituted, disubstituted, trisubstituted, tetrasubstituted, or unsubstituted by the R
