It is an object to provide a carbazole derivative which is useful as a raw material for forming a light-emitting element material which has resistance to repeated oxidation reactions. It is an object to provide a carbazole derivative represented by a general formula (G-1). In the general formula (G-1), each of Ar
1
and Ar
2
represents an aryl group having 1 to 12 carbon atoms such as phenyl, biphenyl, or naphthyl. Also, R
1
represents any one of hydrogen, an alkyl group having 1 to 4 carbon atoms such as methyl, ethyl, or tert-butyl, and an aryl group having 6 to 12 carbon atoms such as phenyl, biphenyl, or naphthyl. Further, the aryl group may have a substituent, or is not required to have a substituent.

An object is to provide a novel anthracene derivative. Another object is to provide a light-emitting element with high luminous efficiency. Yet another object is to provide a light-emitting element with a long lifetime. Still another object is to provide a light-emitting device and an electronic device having a long lifetime by using the light-emitting elements of the present invention. The anthracene derivative represented by General Formula (1) is provided. The ability of the anthracene derivative represented by General Formula (1) to exhibit high luminous efficiency allows the production of a light-emitting element with high luminous efficiency and a long lifetime.
