▎ 摘　　要

NOVELTY - The electrode has a thin film that is provided with a graphene nano ribbon which is provided in the electrode formation area (20). The electrode formation area is provided outside the pattern area of the self-assembled monolayer. USE - Electrode such as source electrode, gate electrode and drain electrode for organic-semiconductor element such as organic thin-film transistor used in planar light source and display apparatus and photoelectric conversion element used in solar cell module and image sensor (all claimed). Can also be used for organic electroluminescent element, electronic tag and LCD element used in computer, TV, mobile telephone, car navigation system and video camera. ADVANTAGE - The organic semiconductor element can be easily manufactured at low cost. The field effect mobility of the organic semiconductor element is improved, so as to improve the response speed of the organic semiconductor element.
