PROBLEM TO BE SOLVED: To provide a composite having electric characteristics similar to precious metal particles by way of a mixture of precious metal coated particles and precious metal particles. SOLUTION: The conductive particle composite consists of precious metal coated particles with smaller average diameter than that of precious metal particles with precious metal coated on the surface of precious metal particles and inorganic fine particles. And it is connected to a manufacturing method of precious metal coated particles by adding precious metal salt solution to dispersion liquid under agitation with inorganic particles dispersed in reducer solution, or a method of manufacturing precious metal coated particles by adding precious metal salt solution and reducer at the same time to dispersion liquid of inorganic particles under agitation.
