To provide an organic transistor which is highly stable in the atmosphere.

The organic transistor includes a gate electrode, a source electrode, a drain electrode, and an organic semiconductor layer. The organic semiconductor layer contains a compound expressed by a formula (1), wherein: Ar1, Ar2, Ar3 and Ar4 represent aryl groups which may independently include a substituent group or univalent heterocyclic groups which may independently include a substituent group; R1 and R2 represent aryl groups which may independently include hydrogen atoms, an alkyl group, a substituent silyl group, and a substituent group or univalent heterocyclic groups which may independently include a substituent group; n is an integer of 1 to 5. When there are a plurality of R1s, they may be the same or different. When there are a plurality of R2s, they may be the same or different.
