Abstract
Abstract Disclosed is a process for the preparation of an electroconductive polymeric material, comprising the steps of forming fine grooves in a substrate, embedding a polymerization reaction catalyst in the fine grooves, and bringing a monomer capable of forming an electroconductive polymeric material into contact with the catalyst embedded in the fine grooves to selectively form fine wiring of the electroconductive polymeric material in the grooves. According to this process, a polymeric material oriented in the longitudinal direction of the fine grooves can be prepared, and therefore, a polymeric material having an excellent electroconductivity can be provided.
