An object of the present invention is to provide a carbazole derivative which is useful in manufacturing a substance having resistance to oxidation. Another object is to provide a carbazole derivative which is useful in manufacturing a novel material with high reliability. Still another object is to provide a material for a light emitting element with high reliability. The present invention is a carbazole derivative represented by the following general formula (1) (where each of Ar
1
and Ar
2
represents an aryl group having 6 to 14 carbon atoms which may include a substitute, Ar
1
and Ar
2
may be either the same or different, and R in the formula represents hydrogen or an alkyl group having 1 to 4 carbon atoms). In addition, the present invention is a material for a light emitting element which includes a carbazole derivative represented by the following general formula (1) as a substituent.
