Abstract:
A conductive sheet comprising conductive composite metal particles in an organic polymeric substance in which the conductive composite metal particles are obtained by coating the surfaces of conductive metal particles with a high-conductive metal, wherein the conductive metal particles have a number average particle diameter of 5 to 100 &mgr;m, a BET specific surface area of 0.01Ã—103 to 0.7Ã—103 m2/kg, a sulfur element content of at most 0.1% by mass, an oxygen element content of at most 0.5% by mass and a carbon element content of at most 0.1% by mass; and the coefficient of variation of the particle diameter is at most 50% and the saturation magnetization of the particles is at least 0.1 Wb/m2.
