Provided are: a semiconductor material for organic transistors which has a high charge mobility, solvent solubility, and oxidation stability, and a good film-forming performance; and an organic thin-film transistor using the same. This organic semiconductor material for an organic transistor is a seven-ring fused heterocyclic compound having a benzene ring at both terminals and a ring, which has a structure in which benzene rings (A) and pyrrole rings (B) are fused in the sequence A-B-A-B-A, between the benzene rings. An alkyl group, an alkenyl group, an alkynyl group, or an aromatic group may be substituted in the fused heterocyclic compound. In the organic thin-film transistor, the above compound is used for a semiconductor layer. |
