To provide a heteroacene derivative which has excellent oxidation resistance and can form semiconductor active phases by a coating method, to provide an oxidation-resistant organic semiconductor material using the same, and to provide an organic thin film.

This heteroacene derivative is represented by general formula (1), wherein, the substituents R1to R18are each identically or differently H, F, a 1 to 30C alkyl group, a 4 to 30C aryl group, a 2 to 30C alkenyl group, or a 2 to 30C alkynyl group; T1and T2are each identically or differently S, Se, P, B, or Al; (l) and (m) are each an integer of 0 or 1; and (n) and (o) are each an integer of 0 to 2.
