PROBLEM TO BE SOLVED: To provide an organic metal complex of a material capable of emitting light by current excitation, and capable of emitting phosphorescence. SOLUTION: The organic metal complex contains a structure represented by general formula (G1) (wherein, X is -O- or -N(R<SP>10</SP>)-; R<SP>1</SP>to R<SP>9</SP>are each one of hydrogen, a 1-6C alkyl group or cycloalkyl group, a 1-6C alkoxy group, a 1-6C alkoxycarbonyl group, a 1-6C acyl group, a 1-6C acyloxy group, a halogen group, a haloalkyl group and a 6-12C aryl group; R<SP>10</SP>is one of a 1-6C alkyl group or cycloalkyl group, a 1-6C acyl group, a 6-12C aryl group and a 4-10C heteroaryl group; and M is a group 9 or group 10 element).
