PROBLEM TO BE SOLVED: To provide a field effect transistor, capable of stably forming an organic semiconductor layer with high crystallinity and orientation over a wide temperature range, from a low temperature, and also exhibiting high mobility. SOLUTION: In the field effect transistor, an organic semiconductor layer contains at least a compound, having a monobenzoporphyrin skeleton expressed by a general Formula (1), where R1 and R2 respectively refer to one selected among a hydrogen atom, halogen atom, hydroxyl group or 1C-12C alkyl group, alkenyl group, oxyalkyl group, thioalkyl group, alykyl ester group and aryl group, at least two of R2 are other than the hydrogen atoms, R3 is at least one selected from the hydrogen atoms and aryl group, and M refers to two hydrogen atoms, metallic atoms or a metal oxide. Adjacent R1 and R2 may be the same as each other or different from each other. COPYRIGHT: (C)2006,JPO&NCIPI
