PURPOSE:To bear various characteristics by selecting the kinds of organic molecules to be used in a simple structure and at low cost. CONSTITUTION:A thin film comprising organic molecules, preferably organic semiconductor is formed on a conductive substrate 1. In such a constitution, when a probe 4 is arranged making a gap 3 to observe a tunnel current using the substrate 1 and the probe 4 as electrodes, the phenomena of increasing the tunnel current and making the organic molecules transparent can be observed by feeding the probe 4 with a potential corresponding to the energy equal to the molecular orbit given to the orbit of the organic molecular film. At this time, the title electrode element can be used as a negative resistance element having the current at this time making the negative resistance. In the concrete, in order to constitute the title element, a negative resistance element can be manufactured by arranging a conductor on both surfaces of a thin film element through the intermediary of an insulator body thin film so as to use this conductor as an electrode.
