Organic semiconductor element and organic electrode

An organic electrode, comprising:

• a laminated film, in which a layer of a tetrathiafulvalene derivative expressed by the following general formula I and a layer of an electron-accepting compound are laminated:
• where X is a carbon atom, a sulfur atom, or a nitrogen atom, and a plurality of X are the same or different from each other;
• and R1 to R16 are each a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, or a substituted or unsubstituted thioalkoxy group, and are the same or different from each other, provided that X is the carbon atom or the nitrogen atom.
