An object is to provide a new fluorene derivative as a good light-emitting material for organic EL elements. A fluorene derivative represented by General Formula (G1) is provided. In the formula, R1 to R8 separately represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, or a substituted or unsubstituted biphenyl group. Further,α1 toα4 separately represent a substituted or unsubstituted phenylene group. Ar1 represents a substituted or unsubstituted condensed aromatic hydrocarbon having 14 to 18 carbon atoms forming a ring. Ar2 represents a substituted or unsubstituted aryl group having 6 to 13 carbon atoms forming a ring. Ar3 represents an alkyl group having 1 to 6 carbon atoms or a substituted or unsubstituted aryl group having 6 to 12 carbon atoms. Further, j, m, and n separately represent 0 or 1, and p represents 1 or 2. |
