Patent ID: 6926751

Claim:
Conductive composite metal particles obtained by coating the surfaces of conductive metal particles with a high-conductive metal, wherein the conductive metal articles are formed from a metallic material selected from the group consisting of iron, nickel, cobalt and alloys thereof, having a number average particle diameter of 5 to 100 μm a BET specific surface area of 0.01×10 3 to 0.7×10 3 m 2 /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 wherein 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/m 2 .
