To provide an organic transistor having high mobility, large current on/off-ratio and superior in storage stability.

The organic transistor has an organic semiconductor layer, which contains at least one kind of compounds represented by general formula (1). In formula (1), X1 to X10 each independently represent for a hydrogen atom, a halogen atom, a straight-chain, branched or cyclic alkyl group, a straight-chain, branching or cyclic alkoxy group, or a substituted or unsubstituted aryl group; and a ring A and a ring B represent a substituted or unsubstituted benzene ring, a substituted or unsubstituted naphthalene ring, a substituted or unsubstituted thiophene ring, or a substituted or unsubstituted benzo[b]thiophene ring.
