To provide a novel heterocyclic compound that can be used as a host material in which a light-emitting substance of a light-emitting layer is dispersed. A heterocyclic compound comprising a dibenzo[f,h]quinoxaline ring and two hole-transport skeletons, where the dibenzo[f,h]quinoxaline ring and the two hole-transport skeletons are bonded to an aromatic hydrocarbon group. A heterocyclic compound represented by the following general formula (G1) is provided.
Note that in the formula, A1 and A2 each independently represent any of a substituted or unsubstituted carbazole skeleton, a substituted or unsubstituted dibenzofuran skeleton, and a substituted or unsubstituted dibenzothiophen skeleton; B represents a substituted or unsubstituted dibenzo[f,h]quinoxaline skeleton; and Ar represents an arene skeleton having 6 to 13 carbon atoms. A light-emitting element including the heterocyclic compound is provided.
