In General Formula (G7), Q represents oxygen or sulfur; each of R15 and R34 independently represents any of hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 7 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms; and Ar represents a substituted or unsubstituted arylene group having 6 to 25 carbon atoms, or a single bond.

Another embodiment of the present invention is a light-emitting element containing any of the above-described organic compounds.

The light-emitting element in the above embodiment includes an EL layer between an anode and a cathode. The EL layer includes at least one of a light-emitting layer, a hole-transport layer, a hole-injection layer, an electron-transport layer, and an electron-injection layer. Note that the EL layer may include another functional layer.

In the above structure, the light-emitting layer preferably contains a light-emitting material.
