It is an object of the present invention to provide a novel triazole derivative. Further, it is another object of the present invention to provide a light-emitting element having high luminous efficiency with the use of the novel triazole derivative. Moreover, it is still another object of the present invention to provide a light-emitting device and electronic devices which have low power consumption. A light-emitting element having high luminous efficiency can be manufactured with the use of a triazole derivative which is a 1,2,4-triazole derivative, in which an aryl group or a heteroaryl group is bonded to each of 3-position, 4-position, and 5-position, and in which any one of the aryl group or heteroaryl group has a 9H-carbazol-9-yl group.
