ABSTRACT:
A conductive layered product is made by adhering an oligothiophene compound to the surface of a polytetrafluoroethylene (PTFE), wherein the surface of said PTFE is oriented by an orientation treatment, and wherein the molecular chains of said oligothiophene compound are oriented and crystallized in the orientation direction of the PTFE, thus improving the orientation of the oligothiophene compound of a low molecular conductive material by a simple method. The oligothophene compound adhered to the PTFE oriented film is oriented and crystallized. A gaseous-phase method and a casting method are acceptable methods for adhering the compound. It is preferable to use oligothiophene compounds with 4-6 polymerization degrees. The oligothiophene compound, in which the .alpha. position at the end of molecular chains is replaced with an alkyl group, can also be used.
