It is an object to provide a conductive organic thin film having organic molecules that include at one end a terminal bonding group that is covalently bonded to a substrate surface, a conjugate bonding group that is located at any portion of the organic molecules and that is polymerized with other molecules, and a polar functional group that does not include active hydrogen and that is located at any portion between the terminal bonding group and the conjugate bonding group, wherein the organic molecules are oriented and their conjugate bonding groups are polymerized, forming a conduction network. The conductivity (ρ) of the conductive organic thin film at room temperature (25° C.) is at least 5.5×10
5
S/cm, and preferably at least 1×10
