Provided is a novel heterocyclic compound which can be used in a light-emitting layer of a light-emitting element as a host material in which a light-emitting substance is dispersed. A heterocyclic compound represented by a general formula (G1) is provided. Any one of R
1
to R
10
represents a substituent represented by a general formula (G1-1), another one of R
1
to R
10
represents a substituent represented by a general formula (G1-2), and the others separately represent hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, or a substituted or unsubstituted biphenyl group. Further, α
1
and α
2
separately represent a substituted or unsubstituted phenylene group or a substituted or unsubstituted biphenyldiyl group, and A
1
and A
2
separately represent a substituted or unsubstituted carbazolyl group, a substituted or unsubstituted dibenzothiophenyl group, or a substituted or unsubstituted dibenzofuranyl group.
