An object of one embodiment of the present invention is to provide a novel oxadiazole derivative as a substance having high excitation energy, in particular, a substance having high triplet excitation energy. One embodiment of the present invention is an oxadiazole derivative represented by General Formula (G1) below.
In General Formula (G1), R
1
represents either an alkyl group having 1 to 4 carbon atoms or a substituted or unsubstituted aryl group having 6 to 13 carbon atoms. In General Formula (G1), R
21
to R
27
separately represent any one of a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms. In General Formula (G1), α represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms. In General Formula (G1), Z represents either a sulfur atom or an oxygen atom.
