A carbazole compound which can be used for a transport layer or as a host material or a light-emitting material of a light-emitting element is provided. Specifically, a carbazole compound which makes it possible to obtain a light-emitting element having good characteristics when used in a light-emitting element emitting blue phosphorescence is provided. In the carbazole compound, the 9-position of one carbazole, the 9-position of the other carbazole, and the 1-position of a benzimidazole skeleton are bonded to the 1-position, the 3-position, and the 5-position of benzene.
