PROBLEM TO BE SOLVED: To provide a surface coating metal nanoparticle that excels in dispersibility in a polar solvent, and that can form a strong sinter structure by heat treatment at a low temperature (concretely at most 350°C) in an inert gas atmosphere.SOLUTION: A surface coating metal nanoparticle includes: a low-melting-point metal nanoparticle that includes at least one metal atom selected from a group consisting of Sn, Bi, Te, and Pb, and in which an average particle size is 1-100 nm; and an 8-22C aliphatic amine disposed to a surface of the low melting point metal nanoparticle. |
