To provide a surface treatment method for obtaining long-term storable dried bodies of fine metal particles, to provide the dried bodies and also to provide a dispersion liquid in which water is added to the dried bodies of the fine metal particles to redisperse the fine metal particles.
The followings are provided: the surface treatment method of fine metal particles characterized in that an agglomerating agent is added to an aqueous dispersion liquid of fine metal particles having surfactants and lipids adsorbed thereon to agglomerate and precipitate the fine metal particles and then the resulting precipitated agglomerates of the fine metal particles are vacuum-dried to obtain a dried material whose fine metal particles can be redispersed in water; the dried bodies of the fine metal particles; the disperse liquid of the fine metal particles; and applications thereof.
