Subjects for the invention are to provide fine metal particles which have surface resistance as low as about 10<2> to 10<4> OMEGA / &squ& , are excellent in antistatic properties, anti-reflection properties, and electromagnetic shielding properties, and are suitable for use in forming a transparent conductive coating film excellent in reliability and durability, and to provide a process for producing the fine metal particles. <??>The invention provides fine metal particles comprising iron and noniron metal, which have an average particle diameter in the range of from 1 to 200 nm and an iron content in the range of from 0.1 to 3.0% by weight. The noniron metal preferably is one or more metals selected from the group consisting of Au, Ag, Pd, Pt, Rh, Ru, Cu, Ni, Co, Sn, Ti, In, Al, Ta, and Sb. In the fine metal particles according to the invention, part of the surface of the fine metal particles may be in the form of an oxide and/or a hydroxide. |
