[Problem] To provide a conductive material that has a conductive polymer adhered uniformly on the surface of a base material so as to achieve a lower resistance value. [Solution] Specifically, provided is a conductive material which is obtained by adhering, as a conductive polymer, PEDOT-pTS to a nylon base material or a base material chiefly consisting of silk or a silk-derived component. Also provided by the present invention are: a method for producing said conductive material, the method comprising (1) an adhesion step for adhering a pTS solution containing an oxidative component and p-toluenesulfonate (pTS) to a base material formed of silk fiber or nylon fiber or a base material coated with sericin or fibroin, and (2) a polymerization step for further adhering 3,4-ethylenedioxythiophene (EDOT) to said base material, to which the oxidative component and pTS have been adhered in the adhesion step, so as to cause a polymerization reaction for generating poly(3,4-ethylene-dioxythiophene)-p-toluenesulfonate (PEDDOT-pTS) to occur in the base material to create a state in which PEDDOT-pTS is adhered to said base material； and a bioelectrode that includes the conductive material.
