PROBLEM TO BE SOLVED: To provide a method of manufacturing functional molecular elements that can discriminatingly manufacture a first functional molecular element having a bias voltage region showing negative differential resistance and a second functional molecular element having diode characteristics, to provide a method of manufacturing a functional molecular device, and to provide a method of manufacturing an integrated element comprising a plurality of kinds of functional molecular elements. SOLUTION: In the method,πelectron conjugated molecules 1 each of which is a kind of linear tetra-pyrrole and has a nearly discoidal center frame part 2 and a flexible side chain part 3 composed of an alkyl group are dissolved in 4-pentyl-4'-cyanobiphenyl and adjusted to a suitable concentration. The solution is stuck to electrodes 5, 6 and liquid crystal solvent molecules are evaporated from the solution to form an array structure 4 of theπelectron conjugated molecules 1 in a self-organizing manner. In this case, the first functional molecular element or a second functional molecular element is discriminatingly manufactured by setting the evaporation temperature to temperature at which liquid crystal solvent molecules form a liquid crystal phase or to temperature at which liquid crystal solvent molecules form a liquid phase.
