To provide a highly integrated device by manufacturing the device using an organic substance independent of crystallinity even when subjected to fine processing of below 0.1 micron associated with the advance of the high density of devices.

A molecule having an insulating functional group and functional groups reactive with the active hydrogen of the surface of a base material at both ends of the molecule is formed into an insulating monomolecular film 5 or an insulating monomolecular accumulated film on the surface of a substrate containing active hydrogen on the surface by a chemical adsorption method, a molecule having a functional group producing a conductive conjugated bond group by polymerization and a functional group reactive with the active hydrogen of the surface of the base material is formed into a monomolecular film 6 or a monomolecular accumulated film by the chemical adsorption method, a molecule constituting the monomolecular film is oriented, and the functional group producing the conductive conjugated bond group in the monomolecular film is polymerized into a conductive monomolecular film 6' or a monomolecular accumulated film.
