There are provided a novel compound having a good field mobility, a method of producing of the compound, an organic semiconductor material containing the novel compound, and an organic semiconductor device. The novel compound which is represented by the following general formula (1), (2), (3) or (4) (where Z represents a sulfur atom or a selenium atom, and R represents a hydrogen atom, an alkyl group or a phenyl group in general formulae) has a structure having two benzene rings of naphthalene bonded with a thiophene ring and a selenophene ring, respectively. These compounds have a conjugate system in molecules due to an interaction between it orbitals, and show a strong molecular interaction through a sulfur atom or a selenium atom contained in a thiophene ring or a selenophene ring in each molecule, thereby having a good field mobility.
