    • A functional molecular element having a structure in which the contact resistance at the interface between a constituting molecule and an electrode can be reduced, the functional molecular element having a specific conductivity, a process for producing the same, and a functional molecular device, are provided. A π-electron conjugated molecule 1, which is one species of linear tetrapyrrole having a substantially disk-shaped central skeleton moiety 2 and a flexible side chain moiety 3 composed of an alkyl group, is dissolved in 4-pentyl-4′-cyanobiphenyl or tetrahydrofuran, and the concentration is adjusted to an appropriate level. This solution is applied to electrodes 5 and 6, and the solvent is evaporated, whereby an array structure 4 of the π-electron conjugated molecules 1 is self-organizingly formed. An adsorbate molecule 9 in the first layer of the array structure 4 is fixed in such a manner that its side chain moiety 3 is adsorbed on a surface of the electrode 5 or 6 and a substantial disk plane of the skeleton moiety 2 is parallel to and adhered to the surface of the electrode 5 or 6. The stacking direction of the π-electron conjugated molecules 1 in the second and subsequent layers of the array structure 4 is controlled by the π-π interaction between the substantially disk-shaped central skeleton moieties 2.
