An object is to provide an organometallic complex that can emit red light. Another object is to provide an organometallic complex having high emission efficiency. Still another object is to provide an organometallic complex that can emit red light with high luminous efficiency. The present invention provides an organometallic complex having a structure represented by the following general formula (G1'). In the formula, Ar represents an aryl group having 6 to 25 carbon atoms; R1 represents any one of hydrogen, an alkyl group having 1 to 4 carbon atoms, and an alkoxy group having 1 to 4 carbon atoms; R2 to R8 each represent any one of hydrogen, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, and a halogen group; at least one of pairs R3 and R4, R4 and R5, and R5 and R6 may be bound to each other to form a ring; and M represents a central metal of Group 9 elements and Group 10 elements.

To provide an organometallic complex by which red-color light emission can be obtained. In addition, to provide an organometallic complex with high light emission efficiency. Further, to provide an organometallic complex by which red-color light emission with high luminous efficiency can be obtained. An organometallic complex having a structure represented by the following general formula (G1) is provided. (In the formula, A represents an aromatic hydrocarbon group having 6 to 25 carbon atoms. Further, Z represents any one of hydrogen, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, or an aryl group having 6 to 25 carbon atoms. In addition, Ar1 represents an aryl group having 6 to 25 carbon atoms. R1 represents any one of hydrogen, an alkyl group having 1 to 4 carbon atoms, or an alkoxy group having 1 to 4 carbon atoms. Further, M is a central metal and represents an element belonging to Group 9 or Group 10.)
