A biscarbazole derivative having a specific group, which is represented by formula (1);
and an organic electroluminescence device in which a plurality of organic thin-film layers including a light emitting layer are disposed between a cathode and an anode, and at least one of the organic thin-film layers include the biscarbazole derivative. The organic electroluminescence device exhibits high emission efficiency and has a long lifetime. In formula (1), each of A
1
and A
2
independently represents a substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms; each of Y
1
to Y
16
independently represents C(R) or a nitrogen atom; each of R groups independently represents a hydrogen atom, etc.; and each of L
1
and L
2
independently represents a single bond, etc.; provided that at least one of A
1
, A
2
and R represents a substituted or unsubstituted fluoranthenyl group, etc.
