wherein in the formula [1], Ar
1
and Ar
2
each independently represent an aromatic hydrocarbon group or a heteroaromatic ring group, R
1
to R
4
are each independently selected from a hydrogen atom or a substituent, R
1
and R
2
and R
3
and R
4
each may form a benzene ring, wherein the benzene ring may have at least one substituent.
An organic compound represented by formula [1] is provided.
Ring A is a polycyclic aromatic hydrocarbon ring having a fluoranthene skeleton and having 16 to 60 carbon atoms and optionally has, as a substituent, a substituted or unsubstituted alkyl group or the like. Rings B

1
and Q
2
respectively represent one of the electron withdrawing groups of the ring B
1
and one of the electron withdrawing groups of the ring B
2
, and are respectively located at an ortho position of the ring B
1
and at an ortho position of the ring B
2
with respect to the ring A.
