A field effect transistor is provided which comprises an organic semiconductor layer comprising a compound having a monobenzoporphyrin skeleton represented by the general formula (1):
wherein R
1
and R
2
are independently selected from the group consisting of a hydrogen atom, a halogen atom, a hydroxyl group, and alkyl, alkenyl, oxyalkyl, thioalkyl, alkyl ester and aryl groups each having 1 to 12 carbon atoms with the proviso that adjacent R
1
may be the same or different and adjacent R
2
may be the same or different and that at least two of R
2
are not hydrogen atoms; R
3
is a hydrogen atom or an aryl group; and M denotes two hydrogen atoms, a metal atom or a metal oxide.
