Zusammenfassung:PROBLEM TO BE SOLVED: To provide indium based metal fine particles and a dispersion sol appropriately usable for forming a transparent and conductive film having an excellent antistatic property and electromagnetic shielding property and also having an excellent manufacturing reliability and cost effectiveness. SOLUTION: The indium based metal fine particles have a 2-200 nm average particle size. The indium based metal fine particles contain indium metal only or one or more kinds of metal components selected from among Sb, Sn, Ag, Au, Zn, Cu, Bi and Cd together with the indium metal. The indium based metal fine particles dispersion sol is obtained by dispersing the indium based metal fine particles in water and/or an organic solvent. In a method for manufacturing the indium based metal fine particles, a reducing agent is added to a mixed alcohol solution containing an indium compound and an organic stabilizing agent and having a ≥40 wt.% alcohol content in the solvent.
