A conductive material according to the present invention includes a polymer having a glass transition temperature (Tg) of 25°C or below and a metal filler containing metal nanowires; and a structure in which wire bundle portions each formed by assembling the metal nanowires are dispersed in the polymer. The conductive material according to the present invention includes the wire bundle portions, in each of which the metal nanowires are assembled. Accordingly, the conductive material is highly extensible, and electrical resistance is not easily increased upon extension. A transducer according to the present invention includes a dielectric layer made of an elastomer, a plurality of electrodes with the dielectric layer interposed therebetween, and wirings each connecting to corresponding one of the electrodes. Either one or both of the electrodes and the wirings are formed of the conductive material.
