To attain the improvement of an electroconductive elastomer composition in its mechanical properties (hardness and tensile strength), conductivity, conductive material retention and corrosion resistance.
Silicone rubber and a hardening agent are combined with conductive materials comprising a metal powder having arborescent shapes and a metal powder of flaky shapes and the resultant mixture is kneaded and crosslinked to obtain a rubber compound. The resultant compound is dissolved in an organic solvent including saturated hydrocarbons (to be converted into ink). Then, the dissolved solution is applied on the surface of, for example, a heat-resistant film as the thickness of the coating film is adjusted, then dried and cured (for example, cured at elevated temperature by drying) whereby a conductive elastomer body composition is formed on the surface of the supported body in a desired thickness.
